How do you clean an epoxy garage floor?

Routine cleaning: sweep or blow out debris, then mop with warm water and a small amount of dish soap. For oil or grease spots, use a degreaser (Simple Green or similar) and a soft-bristle scrub brush. Rinse thoroughly. Avoid citrus-based cleaners, vinegar, and soap with de-icing agents. Never use a steel brush or abrasive scrubber.

What should you NOT use on an epoxy garage floor?

Avoid: citrus-based cleaners (break down the topcoat), vinegar or acidic cleaners, steel wool or wire brushes, high-pressure power washing (can delaminate edges), and any cleaner with de-icing salts or abrasive particles. Stick to neutral pH cleaners, warm water, and soft brushes.

How to Clean an Epoxy Garage Floor | Katy Floors Epoxy

A professionally installed polyaspartic or epoxy garage floor is extremely easy to maintain. Unlike bare concrete, the smooth sealed surface doesn't absorb oil, chemicals, or water. Cleaning takes minutes rather than an afternoon. Here's the right approach.

Routine Cleaning (Weekly or As-Needed)

Sweep or blower: Blow out dust, sand, and debris with a leaf blower or sweep with a soft-bristle push broom. Don't drag metal-edged tools across the surface.
Damp mop: Warm water with a small amount of dish soap (Dawn or similar) works perfectly for routine mopping. Avoid soaps with citrus additives or de-icing agents.
Dry after mopping: The floor dries quickly on its own. You don't need to wipe it — just ensure puddles aren't left standing overnight if you can avoid it.

Cleaning Oil and Grease Spills

Polyaspartic and epoxy floors are highly stain-resistant, but oil and grease that sits for days can leave a residue. Clean spills while they're fresh when possible:

Blot (don't spread) fresh oil with paper towels or a rag
Apply a degreaser like Simple Green, Purple Power, or similar to the spot
Let it sit 3–5 minutes, then scrub with a soft-bristle brush or nylon scrubber
Rinse thoroughly with water

Products to avoid: Citrus-based cleaners (limonene can attack polyurethane topcoats), vinegar or acidic cleaners, steel wool, wire brushes, abrasive scrub pads, and high-pressure power washing along edges or seams. None of these will immediately destroy your floor, but regular use shortens topcoat life.

Tire Marks

Hot tire marks show up as slightly glossy dark streaks — most visible on lighter flake colors. They clean off easily with a degreaser and soft brush. This is different from hot-tire delamination (coating actually lifting) — if you see the coating peeling rather than just a surface mark, that's a product failure, not a cleaning issue.

Salt and Road Chemical Residue

In Katy TX this is mostly a winter concern. Salt tracked in from roads will leave a white residue when it dries. Mop it up with warm water — don't let it sit. Salt is mildly corrosive to some topcoat chemistries if it pools for extended periods.

Deeper Cleaning (Quarterly)

Every few months: sweep thoroughly, then mop with a floor cleaner designed for sealed or coated concrete (Bona Hard Surface Floor Cleaner or similar neutral pH cleaner). Let dry. This removes accumulated thin residue that regular mopping misses.
