Walk-in freezers, commonly found in restaurants and grocery stores, typically see a lot of activity and traffic, which can quickly lead to unkempt floors. It is vital to keep the floors clean in order to ensure a healthy and sanitary freezer environment. Traditional cleaners can not be used as they will freeze upon contact; however, it is not prudent to regularly defrost the freezer just to clean the floors. Use a commercial cleaners on your freezer floor that are specifically formulated to work in freezing temperatures.
Make sure that all products in the freezer are properly sealed and placed on shelves, off the ground.
Dilute the cleaner with water according to the manufacturer instructions. Mix the solution in a mop bucket. Make as much as you anticipate you will need for the floor. Also mix a bit of the solution in a spray bottle for later spot cleaning.
Apply a layer of the solution to the floor with a mop.
Use a stiff-bristle brush to scrub the floor and to lift any soil or gunk. Add more solution to the floor as needed with the spray bottle. Be sure to get into the corners.
Remove the solution and loose soil and gunk by going over the floor with a clean mop and fresh water. If by chance your walk-in temperature is set below -17.8 degrees C, bring it up to -17.8 degrees Cor mopping with fresh water. Below 0-degree temperatures will cause the water to freeze, making your floor icy and slippery.
For larger, industrial freezers, a rotating floor machine or an automatic scrubber can be used to apply the solution and scrub the floor and a wet vacuum can be used to remove the solution.
