Sweep or blow off loose debris, then mop with warm water and a neutral pH cleaner (or plain water for routine cleaning). Avoid anything acidic, anything with ammonia at high concentration, and abrasive scrubbing pads. A polyurea + polyaspartic floor is one of the easiest surfaces in your house to clean — the topcoat is non-porous, so nothing soaks in. Routine cleaning is basically effortless.
Here's the full playbook for keeping a coated floor looking new for the life of the coating.
What's the easiest routine cleaning method?
Dry sweep or leaf blower first, then damp mop with warm water. That's it. No soap needed for regular dust, dirt, or tracked-in snow residue. Once a month in a typical residential garage is plenty.
A leaf blower is actually my favorite tool for garage cleaning. Faster than a broom, gets dust out of corners, and blows debris right out the door. I use one on my own shop floor. If you don't have a leaf blower, a good stiff push broom works fine — the non-porous surface doesn't hold dust the way concrete does, so sweeping is quick.
When do I need actual cleaner?
A few times a year, or whenever the floor starts looking dull from road salt residue. Use a neutral pH cleaner — something labeled pH 6-8, specifically for epoxy or polyurea floors, or a general-purpose floor cleaner like Simple Green diluted per label directions. Mop it on, let it dwell a minute, mop it off with rinse water.
Good neutral-pH options:
- Simple Green (diluted)
- Dawn dish soap (diluted, a few drops per gallon)
- Mild commercial neutral floor cleaner
- Plain warm water for most cases
You don't need specialty coating cleaners from the contractor. Those are overpriced versions of the same general-purpose formulas. Save your money for something else.
What should I absolutely avoid?
A few things can degrade the topcoat over time or immediately:
- Muriatic acid or any strong acid. Softens and damages the topcoat. Never use acidic cleaners on a coated floor.
- High-concentration ammonia. Concentrated ammonia can dull the finish. Dilute household ammonia is usually fine, but I'd stick with neutral cleaners to be safe.
- Abrasive scrubbing pads. Green scratchy pads or wire brushes can micro-scratch the topcoat. Use a microfiber mop or a soft brush.
- Solvents like acetone, lacquer thinner, MEK. Spot cleaning a stubborn spill is okay in a pinch, but prolonged contact can soften the topcoat.
- Pressure washers at close range. The coating will survive a pressure washer, but hitting it from 6 inches at 3000 PSI can drive water into edges or damage the surface. Keep the wand a foot away minimum.
The topcoat is tough — it's rated for chemical resistance against most things. But these are the categories where I've seen damage happen over years of use.
How do I handle specific spills?
Most spills wipe up because the surface is non-porous. Quick guide:
- Oil or grease: Wipe up with shop rags, then mop with warm water and a few drops of dish soap. No staining.
- Antifreeze, brake fluid, windshield washer fluid: Rinse with water. These don't damage polyaspartic at normal concentrations.
- Battery acid: Neutralize with baking soda + water, then rinse thoroughly. Don't let it dwell — this is one of the few things that can etch the topcoat over time.
- Road salt / brine: Rinse with water. Won't harm the coating, but salt residue looks cloudy, so mop it off occasionally.
- Paint: Wipe wet paint immediately with water or mineral spirits. Dried paint can be scraped gently or softened with a mild solvent.
- Rubber scuffs from tire drag: Magic eraser sponge with a little water. Works great.
- Rust from lawn equipment or metal furniture: Mild abrasive like Bar Keepers Friend, light touch, rinse afterward.
Can I use a pressure washer?
Yes, with two conditions: keep the nozzle at least a foot away, and don't use the zero-degree tip. A 25-40 degree fan tip at medium pressure from 12-18 inches is safe and gets road salt buildup off fast. I use one for basement floors and commercial jobs all the time.
For residential garages, a hose and a push broom usually work fine. Pressure washer is overkill unless you've really let it go. If you're going to use one, do a small test area first to make sure you're comfortable with the distance and angle.
What about snow and ice?
Let it melt and drain, or sweep/squeegee it out of the way. The coating doesn't care about cold, salt, or moisture. It was engineered for exactly this. Wisconsin sees 100+ freeze-thaw cycles per year and the polyurea basecoat handles them at 311% elongation.
If you want to be a little extra, squeegee melt water out the garage door after you pull in. Less standing water means less salt residue to mop up later. But it's not necessary.
Do I need to wax or reseal it?
No. Polyaspartic is a self-sealed topcoat — there's nothing to re-seal. Don't apply wax, don't apply "floor polish," don't spray sealer over it. Those products can cause buildup that actually makes the floor harder to clean and can look hazy after a year or two.
If the floor ever starts looking dull in high-traffic paths after 10-15 years, we can do a topcoat refresh — one coat of fresh polyaspartic over the existing system. Rare, but an option. It's a small job compared to a full install.
What if I scratch it?
Minor surface scratches in the topcoat are hard to avoid over 15+ years in a working garage. They're almost always cosmetic — they don't compromise the basecoat or the flake layer. In most cases they're invisible except at certain light angles.
Deep gouges (think: dragging a loaded tool chest across a rough edge) can be spot-repaired. I can come out and re-topcoat a small area if it's really bothering you, but in most cases the flake pattern hides it naturally.
How often should I clean?
Whatever makes you feel good about it. The floor doesn't need much:
- Weekly: Quick dry sweep or blower for loose dust.
- Monthly: Damp mop with warm water.
- Quarterly: Full mop with neutral cleaner, especially after winter salt season.
- Annually: Inspect for any damage, scratches, or spots that need attention.
That's it. The floor was built to take normal garage use — you don't have to baby it. More on what to expect after install in installation day.
What about entry mats and rugs?
Feel free. The coating is non-porous, so nothing seeps through a mat to stain the floor. Rubber, synthetic, or fabric mats are all fine once the coating is fully cured (a week or more after install). If you want to cover a high-traffic area with a mat, go ahead — the floor underneath stays protected.
