Tools: Sponge, mild detergent or vinegar solution


  • Locate: Find the drip pan and hole under the refrigerator.
  • Clean: Empty the pan and clean it and the surrounding area.

Door Gaskets: Ensuring Energy Efficiency and Food Safety in Your Commercial Fridge

Frequency: Inspect every 3 months, replace as needed.

Tools: None for inspection; replacement gasket if needed.

  • Replace: If damaged, follow the manufacturer’s instructions.

Temperature is Key: Ensure Food Safety and Prevent Strain on Your Fridge

  • Daily Checks: Use a standalone thermometer to verify the accuracy of your refrigerator’s built-in temperature display.
  • Safe Range: The ideal temperature range for commercial refrigerators is between 33°F and 40°F (0.5°C to 4°C).
  • Professional Standards: For in-depth guidelines on temperature control in commercial kitchens, refer to ASHRAE standards NOTE: it does cost

Interior & Exterior Cleanliness: Beyond Just the Looks

A clean refrigerator is essential for food safety and preventing foul odors.

  • Tools: Vacuum cleaner, soft brush


  • Clean Filters: Ensure filters are fully clean for optimal flow.
  • Good Surroundings: Check that nothing blocks the vents.

Defrosting (If Applicable): Get Rid of Ice Buildup

Follow your refrigerator’s instructions for the best results.
