You’d be shocked to discover just how dirty commercial freezers get. Given the nature of what you store inside them, cleaning a walk-in freezer floor cannot be taken lightly. That’s why we’re going to show you how to clean a walk-in freezer floor in this guide.
From supplying the right equipment and supplies to walking you through how to clean a commercial freezer floor step-by-step, SweepScrub is your one-stop shop for all your commercial floor care needs.
Most of the issues in walk-in freezers can be traced back to temperature cycling. Warm air works into the cold environment every single time you open the door. It hits the floor and creates condensation. That moisture freezes, thaws, and then refreezes.
The end result is a slippery film that traps anything that comes into contact with it. Could be grease from stored food items pooling on the floor, or foot traffic brought in from outside.
Either way, proper cleaning cannot be taken lightly. The FDA Food Code mandates regular walk-in freezer floor cleaning to prevent food contamination.1 So, let’s get into the best way to clean a walk-in freezer floor below.
You might have planned on using a push broom and mop for the process. We don’t advocate for these more manual methods, even if your walk-in freezer is relatively small. They just spread mess around and don’t achieve a thorough clean.
A floor sweeper machine picks up all the little crumbs and particles on your freezer floor that would otherwise get ground in during the next step (scrubbing).
There are compact, nimble, and affordable floor sweepers like the Karcher EB 30/1 12” Floor Sweeper. Or, you can upgrade to something a bit bigger for larger freezers like the Viper PS480 28” Floor Sweeper.
Mops never actually clean anything. They spread dirty water around and leave a film on your freezer floor. A commercial walk-behind floor scrubber is a better solution for cleaning a walk-in freezer floor.
We recommend the Tornado Mop Microburst for smaller freezers with its 17.5” cleaning path and 1.3-gallon tank. It’s easy to maneuver around. The SweepScrub 26”, 22-gallon floor scrubber is a step up for more expansive commercial freezers.
Now, what can I use to clean a walk-in freezer floor that won’t put my inventory at risk? It’s imperative that you select food-safe degreasers and neutral pH cleaners. These are your safest option for cleaning a walk-in freezer floor around food.
Your machine will come into play here as well. You need a low-foam detergent for pairing with a scrubber. Excessive foam will just clog the recovery tank and impact suction, leaving behind a nasty film. Obviously don’t use anything heavily scented, as that could transfer over to food.
Here’s the full step-by-step guide on how to clean a walk-in freezer floor.
You need to pull on slip-resistant boots to stay upright on wet or icy surfaces. Insulated waterproof gloves are a must to protect yourself from the cold and cleaning chemicals, too. Most protocols call for eye protection as well, especially while handling detergent.
Shut the unit down and give it time to warm up. This implies you’ll have moved any sensitive food items to a new location, obviously. Or that you’re doing a deep cleaning with the freezer already empty between inventory batches (or seasons).
You just don’t want to clean the freezer floor while it’s still “freezing.” Not only is it uncomfortable, but the cleaning solution will freeze on contact. There may be a thin layer of ice on the floor that is keeping grime underneath it, too.
This goes back to what we just talked about. While you’re getting inventory out of the freezer, take shelving out as well. You want unobstructed access to the freezer floor for cleaning.
Clean all loose debris first with your sweeper. Otherwise, you’ll end up grinding particles into the freezer floor when you start scrubbing.
Don’t want to use separate machines for sweeping and scrubbing the floor? You can consolidate your cleaning equipment with a floor sweeper scrubber, saving time, money, and storage space. The Tornado Vortex 13” 1-gallon Sweeper-Scrubber is a great choice.
This is the real step on how to clean a commercial freezer floor. Fill your floor scrubber’s solution tank with water first, then the cleaning chemical. Adhere to the manufacturer’s recommended dilution rate.
Then, lower the squeegee and ensure you have the proper brush/pad attached to your machine. You can begin working in straight, overlapping passes. The scrubber does all the heavy lifting. You just guide it in the right direction. This is the best way to clean a walk-in freezer floor.
Some floor scrubbers (bigger ones, to be exact) don’t reach into corners very well. Not much of an issue with something like the Tornado Mop Microburst, though.
At any rate, handle the finishing touches in the corners and wall-floor joints with a stiff-bristled brush if need be. Scrub by hand, then squeegee the dirty water towards the drain or pick it up with a wet vac.
