***How to Clean Your Commercial Ice Machine: A Step-by-Step Guide***

(This article is not intended to be a replacement for the manufacturer’s suggested methods so please consult the owner’s manual for more elaborate directions specific to the brand of your machine!)


Step 1: Gather Your Supplies

Before you start, make sure you have the following on hand:

– Ice machine cleaner (nickel-safe if your machine a nickel-plated evaporator; if not, consult your owner’s manual)

– Sanitizer (quaternary ammonia is the industry standard as bleach can wreck your internal components and void your warranty)

– Soft cloths or sponges

– Bucket

– Gloves

– Clean water


Step 2: Power Down and Empty the Machine

Safety first! Turn off and unplug your ice machine. Remove any ice from the bin and discard it. This ensures that you’re starting with a clean slate. (PSSSST! Perfect time to wash and sanitize that ice storage area too!)

Take out any removable parts, such as the ice bin, water trough, and any other components specified in your machine’s manual. This makes it easier to clean every nook and cranny.


Step 4: Clean the Removable Parts

Mix your ice machine cleaner with water according to the manufacturer’s instructions. Soak the removable parts in the solution for the recommended time. Use a soft cloth or sponge to scrub away any residue. Rinse thoroughly with clean water and set aside to dry.


Step 5: Clean the Interior

Using the same cleaning solution, wipe down the interior surfaces of the ice machine. Pay special attention to areas with visible buildup. Be gentle to avoid damaging any components. Rinse with clean water and dry with a soft cloth.


Step 6: Sanitize

Prepare a sanitizing solution as per the instructions on your sanitizer. Apply it to all interior surfaces and removable parts. Allow it to air dry completely. This step is crucial for killing any lingering bacteria or mold.


Step 7: Reassemble and Restart

Once everything is dry, reassemble your ice machine. Plug it back in and turn it on. Run a couple of cycles and discard the first batch of ice to ensure any remaining cleaner or sanitizer is flushed out.


Step 8: Regular Maintenance

To keep your ice machine in tip top shape, clean it every 3 to 6 months, or more frequently if it’s in constant use or if you’re in an area with hard water and/or high mineral content. You may have forgotten about that filter, but now is a good time to get that filter changed too… which your local food service equipment provider probably carries, so double check with the MFR for compatibility before mixing brands).

Regular maintenance prevents buildup and ensures your ice is always safe to consume.


And there you have it! A clean ice machine means happy customers and a happy business. Keep it cool and may your ice always be pristine.

Picking Your Food Truck

Think finding the perfect food truck is all about the menu? Think again! Idaho’s roads, weather, and tricky parking rules mean the wrong truck can leave you broke down before you even break even. Don’t let picking your truck be the roadblock that ends your food truck dream! Here’s why the decision is tougher than it seems…

New vs. Used

A used truck can save you money upfront, but hidden mechanical problems could wipe out those savings and leave you parked for months while you wait for repairs. Worse, those breakdowns often happen at the worst time – right when a big festival crowd is getting hungry! What about customization? Depending on the truck’s age and setup, adding the equipment you need for your dream menu might be impossible, and that limits your future growth.

However, used isn’t always a bad decision!

Size Matters

Bigger isn’t always better. Think about where you’ll be operating. Narrow streets and crowded festivals favor a more compact setup, but can you make YOUR dream menu work in a smaller space? A bad layout means long waits for customers AND food waste… nobody wants that!

Equipment and Layout

Your menu dictates your kitchen. Make sure there’s a fit between what you want to serve and the equipment your truck can house. Efficiency is KEY, but it’s about more than finding fitting ovens. The wrong layout turns cooking into chaos, especially on busy nights. BSR can help… Don’t just wing it!

Branding Space

Your truck is a rolling billboard. Ensure there’s ample room for your logo, menu, and any catchy designs to attract those Idaho crowds.

Pro Tip

Before you commit, check local regulations. Some Idaho cities might have restrictions on truck size or emissions, impacting your choice.

Navigating Regulations and Permits

Idaho might be known for its friendly vibe, but when it comes to food truck regulations, you’ve still got to play by the book. Here’s how to stay on the right side of the law:

Health Department Approval:

Safety first! Getting the green light from the health department is non-negotiable. This means your food truck needs to meet Idaho’s food safety standards, from storage temperatures to sanitation practices. Again BSR can make sure you are compliant.

Business Licenses:

You’re not just a chef on wheels; you’re a business owner. Secure a business license from the city or county where you’ll be operating. Each area might have slightly different requirements, so do your homework.

Special Permits:

Depending on your location and type of food, you might need additional permits. For example, selling alcohol or operating in certain public spaces could require extra paperwork. You can check if you need special permits here

Parking and Zoning:

Not all spots in Idaho welcome food trucks with open arms. Research local zoning laws to know where you can park your truck without running afoul of the law. Idaho Falls might differ from Boise so it’s important to check the city you are in.

Keep a checklist and start early. Some of these permits have a lead time, so you’ll want to get the ball rolling well before your planned launch date. We have a comprehensive guide on all the licenses and permits you’ll need for a restaurant, whether it’s a food truck or brick and mortar. Opening a restaurant in Idaho.

Knife Care: The Essential Guide for Your Commercial Kitchen

Knife Care: The Essential Guide for Your Commercial Kitchen

Knife Care: The Essential Guide for Your Commercial Kitchen


Section 1: Why Blade TLC Matters (Your Knives Aren't Just Tools, They're Investments)

A trusty chef’s knife is more than just a sharpened hunk of metal. It’s an extension of your hand in the kitchen – a precision tool and, when cared for correctly, a culinary companion for years to come. Dedicating a little time to proper knife care might seem like extra effort, but trust us, it pays off in spades:

Sharpening knife on stone


A well-maintained knife slices effortlessly, minimizing bruising and preserving delicate ingredients. Think clean cuts of tomato, not sad squishing.


A dull blade sounds counterintuitive, but it’s far more dangerous! You need to apply excessive force, increasing the risk of slippage and potential cuts.


Replacements ain’t cheap. Good quality knives, with proper care, can last decades. Those cheap sets get dull quickly and end up as landfill waste.

Food Joy:

Cooking is simply more enjoyable when your tools work with you, not against you. Sharp knives cut down on frustrations and help you enjoy your kitchen time.

Section 2: Knife Anatomy 101 (Understanding Your Blade for Better Care)

It seems obvious, but to truly master knife care, you need to understand what you’re working with. Don’t worry, no full anatomy exam – just the key parts that impact how you use and treat your knives:

The Tip:

That pointy end! Perfect for delicate precision work, like scoring or piercing. Treat it gently because tips can chip with misuse.


The Edge:

Edge of knife highlighted

This is the business end, the sharp slicing part. Blade angles and edge types vary widely, affecting what a knife is best used for.

The Spine:

Spine of knife highlighted

The thick, unsharpened top of the blade. Provides strength and balance, and sometimes has measurements printed on it (handy!).

The Heel:

Heel of knife highlighted

The widest part of the blade near the handle. Built for power cuts through tougher ingredients.

Bolster (on some knives):

Bolster of knife highlighted

Thick junction between blade and handle. This offers protection for your fingers and balance. Not all knives have this.

The Tang:

Tang of knife highlighted

This is the metal of the blade extending into the handle. A “full tang” means it goes the full length for maximum strength.

The Handle:

(Wood, plastic, etc.) Where you grip. Variety is huge! Care will depend on what your knife’s handle is made from.

Handle of knife highlighted

Why Does This Matter?


You’ll understand why the bolster area needs extra attention to prevent food buildup.


Blade angles matter depending on your knife’s purpose. We’ll dig into this deep later.

Respecting limits:

A delicate paring knife with a thin tang isn’t built for hacking through bones.

Section 3: Daily Care: Your Knife's Best Practices

You don’t need fancy routines to keep your knives in good shape. These daily habits might seem small, but they make a huge difference in your blade’s performance and lifespan:

Hand washing Knife

Hand Wash ONLY:

Dishwashers are brutal. The abrasive detergents, rattling around, and heat cycles will degrade your knife’s sharpness and can damage the handle. A little love with warm soapy water and a soft cloth goes a long way.

Dry Immediately:

Leaving a knife wet invites rust, even on stainless steel. Dry with a clean dish towel right after washing, paying close attention to the area where the blade meets the handle.

Don’t Soak:

Letting knives mingle dirty in a sink is a big no-no. It dulls the edge and exposes your blades to potential nicks and dings from other dishes.

Cutting Board Basics:

Cutting directly on hard countertops like granite or ceramic ruins edges fast. Always use wood or plastic cutting boards – your knives and kitchen surfaces will thank you.

No Twisting or Prying:

Knives are for controlled slicing and chopping. Using them to pry open cans or twist apart frozen items puts extreme stress on the blade and risks ruining it.

Proper Storage:

Tossing your knives haphazardly into a crowded drawer spells disaster! Dings and chips lead to quicker dulling and premature rusting. We’ll cover best storage options later.

A Note on Steel: Most blade materials are some variety of steel. Even “stainless” needs the love. Carbon steel is extra reactive, developing a unique patina over time. More on specific steels later.

Section 4: Cleaning Deep Dives (When Soap and Water Isn't Enough)

While your everyday knife care focuses on quick, preventative washes, sometimes more intensive cleaning is needed. Here’s when to deep dive and how to tackle those situations:

Dirty Knife

Stuck-On Gunk:

Happens to the best of us! Dried-on dough, caked-on sauces… don’t panic. A little soaking in warm, soapy water usually loosens stubborn debris enough for gentle scrubbing. For super tenacious buildup, a paste of baking soda and water left on the problem area for a few minutes can work wonders.

Stubborn Stains:

Some ingredients, like berries or onions, can leave their mark temporarily. A sprinkle of baking soda with enough lemon juice to form a paste works as a gentle abrasive and a natural lightener for surface stains.

Deep Grime & Rust:

In neglected blades, soaking and gentle scrubbing might not be enough. Bar Keepers Friend (powder form), with its mild oxalic acid, tackles heavy buildup with care. Severe rust might require very fine-grit sandpaper for removal, but this is risky and often necessitates professional services.

Wood Handle Woes:

Wood handles need care beyond the blade. To combat drying out, occasional treatment with food-grade mineral oil keeps them supple. Avoid storing wood-handled knives in extremely damp areas.

A note on disinfecting: Hot water and a good scrub go a long way. If concerned about pathogens (raw meat prep), a diluted bleach solution wiped off immediately is safe on stainless steel but damaging to carbon steel or reactive metals.

Section 5: Honing vs. Sharpening: Your Knives Need Both (But Not at the Same Time)

Knife care can be confusing, especially when you hear “honing” and “sharpening” used almost like they mean the same thing. But there’s a big difference, and understanding it will save your blades – and maybe your fingers too!

Chef Honing Knife

Honing: Quick Edge Tune-Up

See a chef swipe their knife along a steel rod? That’s honing. It doesn’t actually remove any metal. Think of your knife’s edge like a row of tiny teeth. With use, these teeth get bent out of alignment. Honing gently pushes them back into place, restoring that satisfying “bite”. Honing is something you can (and should!) do often.

Sharpening: It’s a Grind

Sharpening actually removes a tiny bit of metal from the blade to create a brand new, razor-sharp edge. Over time, honing alone isn’t enough, and that’s when sharpening steps in. Sharpening requires tools like whetstones, specialized electric sharpeners, or the services of a pro.

When to Hone, When to Sharpen: The Fingernail Test

Not sure if your knife is dull or just a little “off”? Try this: very lightly drag the blade’s edge across your fingernail (carefully!). If it slides without catching at all, your knife needs sharpening. If you feel a slight catch, try honing first, then retest.

How Often is Right?

  • Honing: You can hone before or after each use for maximum sharpness. It’s quick and extends the time between sharpenings.
  • Sharpening: Frequency depends on how often you use your knives and the type of steel. Most home cooks with heavily used knives can get by with 1-2 professional sharpenings per year.

Can I Sharpen My Own Knives?

Technically, yes. But if you want to keep your knives in top shape, there are a few things to keep in mind:

  • Whetstone Woes: Sharpening on a whetstone is a skill that takes practice. If you get the angle wrong, you can damage your blade.
  • Pull-Through Perils: Those cheap “pull-through” sharpeners you see are tempting but often overly aggressive, shortening your knife’s lifespan.
  • Pro-Power: For high-value knives, or if you’re nervous about DIY, a professional sharpening service is the safest bet.

Section 6: Storage Savvy (Protect Your Investment)

How you store your knives matters way more than you might think. It’s about safety, preventing edge damage, and maximizing their lifespan. Here’s what to do (and the mistakes to avoid at all costs)!

Hazard Symbol overlaid a junk drawer

The “Don’ts”

The Junk Drawer:

This is your knife’s worst nightmare! Not only is your blade banging around and dulling against who-knows-what, there’s the serious risk of cutting yourself rummaging in there.

Tossing on the Counter:

Edges get nicked, moisture from the air invites rust, and it’s an accident waiting to happen.

The “Do’s”

Magnetic Wall Strip:

Stylish AND useful! Your knives are accessible, dry, and the blades remain pristine with no contact other than the handle.

In-Drawer Block:

If counter space is tight, the slots ensure safety and minimal blade-on-blade action. Just beware of cheap wood that traps moisture.

Knife Rolls/Cases:

Perfect for pros on the move or if you own several showpiece knives. Ensure each knife has its own slot for maximum protection.

Edge Guards:

If the drawer must be your current solution, individual protective sheaths help. Not ideal long-term, but better than nothing!

Additional Notes:

  • Humidity Matters: Even stainless steel needs a stable environment. Very humid kitchens might necessitate extra vigilance against rust.
  • The “Best” Option: This depends on your kitchen setup and needs. A pro chef with precious knives will have different ideal storage than a home cook with a trusty pair.

Section 7: Telltale Signs (When Your Knife Needs Pro Help)

Even with your newfound dedication to excellent knife care, there are times when it’s best to turn to the professionals for restoration and a razor-sharp edge:

Professional Sharpening of Knives

  • Severe Nicks and Chips: Sometimes, accidents happen. A dropped knife on a tile floor or hidden bone can cause real damage to the blade. A good sharpening service can often smooth out and restore, extending the blade’s life.
  • Warping or Bending: This means the metal itself has lost structural integrity. Unfortunately, not something any kind of sharpening can fix.
  • The ‘Try This!’ Test Fails: You’ve washed, honed, and maybe even given a basic sharpening a go and… things still feel dangerously dull. Time for a professional to assess the state of your blade.
  • High-Value Knives: Your grandfather’s vintage chef knife or the Japanese blades you splurged on deserve extra TLC. Professionals will use the sharpening method most appropriate for the specific type of steel and edge profile.
  • Beyond Your Comfort Zone: Sharpening on whetstones is an acquired skill. If the thought of it intimidates you, there’s absolutely no shame in utilizing skilled sharpeners!

Where to Find Reputable Sharpeners:

  • Word of Mouth: Local butchers, culinary programs, or high-end kitchen stores often have good leads.
  • Online Search: Look for services that specialize in knife sharpening with transparent pricing. Check if they offer mail-in options (handy if your area is limited).

Final note: Even the best pro sharpening shouldn’t be done weekly. That’s where your day-to-day care and honing skills shine!

Optimize Ice Bridge Thickness

Optimize Ice Bridge Thickness


Learn how to Optimize Ice Bridge Thickness! In the realm of commercial ice production, the ice bridge plays a pivotal role in ensuring the quality and consistency of ice cubes. An ice bridge, the slender layer of ice that forms between individual cubes, requires precise adjustment to maintain the perfect balance. Too thick, and the cubes won’t separate at harvest; too thin, and they may break apart prematurely. This article delves into the technicalities of ice bridge adjustment, offering actionable advice and manufacturer-specific instructions to optimize your ice machine’s performance.

Quick House Keeping: IMPORTANT!

Some manufactures will void your warranty for adjust or changing the ice bridge. So make sure to double check before you start changing things. There will be links to warranty pages to the manufactures we cover in this blog at the bottom.

Understanding the Ice Bridge

Optimizing Ice Bridge Thickness is crucial for the structural integrity of ice cubes during the freezing and harvesting phases. It’s formed as water freezes in a grid pattern, with each cube slightly connected by this ice bridge. The thickness of this bridge is determined by the distance between the ice-making grid and the machine’s sensor. Adjusting this distance allows you to control the bridge’s thickness, impacting the ice’s final quality.

DIY Adjustments: Proceed with Caution

While manufacturers often recommend professional servicing for adjustments, understanding the basics can empower you to make minor tweaks, especially if your warranty period has lapsed. Here’s a general guide:


  • Identify the ice thickness sensor: This component is usually located near the ice-making grid.


  • Adjust the sensor: Moving the sensor closer to the grid results in a thinner bridge, while moving it away thickens the bridge. Adjustments should be made in small increments to avoid drastic changes.


  • Test and retest: Allow your machine to complete a few ice-making cycles after each adjustment to accurately assess the impact on ice bridge thickness.

In-Depth Manufacturer-Specific Adjustment Tips

In the realm of commercial ice production, the ice bridge plays a pivotal role in ensuring the quality and consistency of ice cubes. An ice bridge, the slender layer of ice that forms between individual cubes, requires precise adjustment to maintain the perfect balance. Too thick, and the cubes won’t separate at harvest; too thin, and they may break apart prematurely. This article delves into the technicalities of ice bridge adjustment, offering actionable advice and manufacturer-specific instructions to optimize your ice machine’s performance.

Manitowoc logo

Manitowoc ice machines are known for their reliability and ease of maintenance, including bridge thickness adjustments.

  • Locate the ice thickness sensor near the ice grid; it’s held in place by a screw.
  • To reduce the ice bridge thickness, turn the screw counterclockwise. For a thicker bridge, turn it clockwise.
  • Manitowoc recommends adjusting in quarter-turn increments to avoid over-adjustment.
  • After each adjustment, allow the machine to complete at least two full ice-making cycles to evaluate the new bridge thickness.
  • Keep in mind, unauthorized adjustments might affect warranty claims, so it’s crucial to consult the service manual or a professional if in doubt.

Hostizaki Logo

Hoshizaki’s unique approach involves a float switch instead of a direct sensor adjustment, influencing the water level and, consequently, the ice bridge thickness:

  • After accessing the interior, locate the float switch, typically a white, cylindrical component connected to the water reservoir.
  • Adjusting the float’s position up or down alters the water level for the next freeze cycle, affecting the ice bridge thickness.

Secure the float in the new position and monitor the ice over several cycles to ensure the adjustment meets your needs.

Ice-O-Matic Logo

Ice-O-Matic simplifies the adjustment process with its Water Level Adjustment Arm, providing a straightforward method to control ice bridge thickness:


  • The adjustment arm is usually located behind the sump and splash curtain inside the machine.
  • Moving the arm up decreases the ice bridge thickness, while moving it down increases it.
  • After adjustments, it’s important to let the machine run through a few cycles to assess the impact on ice quality.

Scotsman Logo

Scotsman offers a user-friendly approach to adjusting the ice bridge on their models, particularly on undercounter units like the CU0415, CU0715, and CU0920. These machines feature:


  • An electronic bridge adjustment button located on the control panel, eliminating the need for manual screw adjustments.
  • Simply pressing the “+” or “-” buttons will adjust the ice thickness.
  • It’s advisable to make small adjustments and observe the results over a few cycles to ensure the desired ice quality is achieved.

Koolaire Logo

Koolaire machines offer a direct way to adjust the ice bridge thickness through the ice thickness float switch adjuster:


  • This adjuster is typically found beneath the reservoir, often on the left side.
  • Turning the adjuster clockwise increases the ice bridge thickness, whereas turning it counterclockwise reduces it.
  • Koolaire recommends aiming for a bridge thickness of about 1/8-inch for optimal performance.
  • As with other machines, it’s vital to allow a few ice-making cycles post-adjustment to verify the effectiveness of your tweaks.


Adjusting the ice bridge thickness in your commercial ice machine can significantly impact the quality and consistency of the ice produced. By understanding the specific adjustment mechanisms provided by manufacturers like Manitowoc, Scotsman, Hoshizaki, Ice-O-Matic, and Koolaire, you can ensure your machine operates optimally. Remember, while making these adjustments, it’s crucial to proceed with caution, respect warranty terms, and seek professional help if unsure.

    • Water Flow and Pressure: Begin by verifying that your establishment has adequate water pressure feeding into the ice machine. Low water pressure can lead to incomplete ice cube formation. A pressure gauge can be helpful in this assessment.
    • Water Inlet Valve Inspection: Examine the water inlet valve for any signs of wear, damage, or blockage. If the valve is not fully opening, it can restrict water flow, resulting in thin or hollow ice. Cleaning or replacing the valve may be necessary.
    • Water Distribution System: Ensure that the water distribution system over the evaporator plate is functioning correctly and is not clogged. Proper distribution is crucial for even ice formation. Clean any blocked nozzles or channels to restore full coverage.

Water Leakage Issues

In-Depth Solutions:

    • Water Inlet Valve: Check the water inlet valve for leaks. A faulty valve can cause water to drip continuously into the machine, leading to leaks. Replacing the valve may resolve the issue.
    • Inspecting Supply and Drain Lines: Carefully inspect all water supply and drain lines connected to your ice machine for signs of leakage, wear, or damage. Even small cracks or loose connections can lead to significant water leakage. Repair or replace lines as needed.
    • Ice Bin Alignment: Ensure the ice storage bin is properly aligned under the ice machine to catch ice without spillage. Misalignment can cause water to leak out from the sides.

Ice Thickness Probe Calibration and Cleaning

In-Depth Solutions:

    • Cleaning the Probe: Over time, the ice thickness probe can become coated with mineral deposits, affecting its ability to accurately gauge ice thickness. Gently clean the probe with a soft cloth and a Manitowoc-approved cleaning solution. Rinse thoroughly and dry before reattaching.
    • Calibration: Follow the manufacturer’s instructions to calibrate the ice thickness probe. Incorrect calibration can lead to ice that is too thin or too thick. If you’re unsure of how to calibrate the probe correctly, it may be wise to consult with a Manitowoc technician.
    • Proper Alignment: Ensure that the ice thickness probe is correctly aligned with the evaporator plate. Misalignment can cause the machine to misread ice thickness, leading to improper ice production. Adjust the probe’s position as necessary according to the Manitowoc service manual.
