  2. Gather all needed materials and cleaning solutions.
  3. Depending on the size of your walk-in freezer, you may want to consider cleaning it in smaller sections.
  4. Use a stiff bristle brush to loosen dirt and dust from interior fan units. Vacuum to remove lingering debris.

For Optimal Walk-in Freezer Performance

If you want consistently cold temps with fewer repair surprises, it’s not enough just to clean a walk-in freezer; ongoing maintenance is important too. Keep your unit in top shape by following the expert suggestions below.

Doors − Close freezer doors when not in use. Doors that are propped open can make your equipment work harder to keep food cold, costing you money. Check door sweeps and gaskets for wear and make sure they seal tightly. Inspect door hinges quarterly and lubricate as needed (unless self-lubricating).

PRO TIP:  Monitor freezer temperature daily. Big Fluctuations could mean an issue needs to be addressed.

Floors − Sweep and mop floors regularly with Clean Freeze Freezer Cleaner to remove food or debris that can spoil or attract pests. Take care of freezer spills with Clean Freeze as soon as they happen − liquids can freeze quickly, potentially causing slips-and fall accidents.

PRO TIP:  Keep freezer aisles clean and boxes neatly stacked. Good organization will save time searching for products and allow you to take quick inventory.

Lights − Freezer lights produce heat, so turn off when not in use. Adding a pilot light to your switch can indicate if inside lights are on without the need to open the door and let warm air in.

Fans and Condensers – Keep outside units free of plant growth, trash or anything that could impede airflow. Check for damage or decay in the insulation on suction lines between the condensing unit and evaporator coils. Coils may need to be cleaned more often if they are located outside, so inspect regularly. Examine fan motors to ensure they are running at optimal speed.

PRO TIP:  Don’t stack food or boxes too close to the thermostat sensing bulb. Closely placed items can give a false temperature reading.

Drain lines − Have freezer drain lines cleaned and inspected annually by a professional. Clogged lines can make your unit run less efficiently.

Electrical − Loose wires and faulty connections can be an energy drain. Have an electrician inspect for any needed repairs that could be costing you money.

It isn’t complicated to clean a walk-in freezer. A little know-how with the right cleaning and maintenance products goes a long way toward keeping your investment working efficiently with a longer life span. Regularly scheduled maintenance and inspections will save you money in the long run and help you glide through any problems that may arise.
