Your epoxy garage floor is one of the best investments you can make in your home. It looks sharp, resists stains, and is far easier to maintain than bare concrete — but only if you give it a little regular attention. Routine cleaning protects the coating from grit, road salt, oil, and chemical buildup that can dull the finish over time.
The good news? You don’t need expensive equipment or a professional cleaning service. All it takes are a few common household items and about 20 minutes. Watch the video below for a quick visual walkthrough, then read on for the full step-by-step guide.
Watch: How to Clean Your Epoxy Garage Floor
What You’ll Need
- Broom
- Bucket
- Microfiber mop
- Stiff-bristle deck brush
- Squeegee
- Neutral pH floor cleaner (such as Zep, or a mild dish soap)
- Water (hose or bucket)
That’s it — no rentals, no specialty chemicals, and no professional equipment required.
Step-by-Step: How to Clean Your Epoxy Garage Floor
Step 1: Start with a Dry Sweep
Before introducing any water, do a thorough dry sweep of the entire floor. Clear away loose dirt, debris, gravel, and leaves. Skipping this step means you’ll just be pushing muddy grit around once the floor gets wet — and grit is one of the main culprits behind scratches in the epoxy coating.
Step 2: Wet the Floor
Use a garden hose or a bucket of water to wet the floor down. This initial rinse loosens surface-level dirt and begins softening any caked-on buildup. For floors that haven’t been cleaned in a while, this step alone can make a big difference before you start scrubbing.
Step 3: Tackle Stubborn Dirt and Grease with a Deck Brush
For tougher areas — oil drips from vehicles, road salt residue, or mud tracked in from outside — use your deck brush to scrub directly on those spots. Work in circular motions. A stiff-bristle deck brush has enough force to break up grease and embedded grime without scratching or damaging the epoxy surface.
Step 4: First Rinse and Squeegee
Rinse the floor with fresh, clean water to wash away the dirty water you’ve loosened. Then squeegee the water toward your garage door or a floor drain. Don’t let dirty water pool and dry — it’ll leave behind a residue that dulls the finish.
Step 5: Scrub with a Neutral Floor Cleaner
Mix your neutral pH floor cleaner with water in a bucket according to the product’s instructions. Using the soapy solution and your deck brush, scrub the entire floor surface. This is the key cleaning step — it lifts salt, fine dust, and lingering grease from the coating. Important: always use a neutral or pH-balanced cleaner. Avoid bleach, acids, citrus-based cleaners, and anything solvent-based — these can cloud, soften, or discolour your epoxy topcoat.
Step 6: Second Rinse and Squeegee
Rinse the floor again with clean water to remove all soapy residue, then squeegee away the excess. Leaving soap on the floor is the most common reason epoxy floors look streaky or hazy after cleaning — so don’t rush this step.
Step 7: Finish with a Microfiber Mop
Complete the clean by going over the floor with a dry or lightly damp microfiber mop. Microfiber picks up the fine dust and particles that a squeegee can’t capture, and it leaves your floor with a clean, polished-looking finish. This final step is what makes the floor truly shine.
Pro Tips for Keeping Your Epoxy Floor in Top Shape
- Clean up spills right away. Oil, transmission fluid, and chemical spills are far easier to remove when fresh. Left to sit, they can penetrate the coating or cause staining.
- Use drip pans under vehicles. If your car or truck has a slow leak, a drip mat protects the floor between cleanings.
- Sweep weekly between full cleans. A quick dry sweep once a week prevents grit buildup that can scratch the surface over time.
- Place entry mats at the garage door. A mat at the entrance traps road salt and gravel before it gets dragged across the floor.
Frequently Asked Questions
Can I use a pressure washer on my epoxy garage floor?
Yes, with some care. A pressure washer can tackle heavy buildup effectively, but use a wide-angle nozzle (40° or wider) and keep the pressure at or below 1,500 PSI. High-pressure narrow jets can lift the coating at seams or edges. For regular weekly or monthly cleaning, a hose and deck brush are gentler and perfectly sufficient.
What floor cleaners are safe for epoxy?
Stick to neutral pH cleaners. Good options include Zep Neutral Floor Cleaner, diluted Simple Green, or a small amount of dish soap mixed in warm water. Avoid anything acidic (vinegar, citrus degreasers, muriatic acid) or solvent-based (acetone, ammonia, bleach). These can soften or discolour the topcoat over time.
How often should I clean my epoxy garage floor?
A thorough scrub-and-mop cleaning once a month keeps most garage floors in great shape. If your garage sees heavy use — lots of vehicle traffic, winter salt, outdoor projects — consider cleaning every two to three weeks. A quick dry sweep in between full cleanings goes a long way toward protecting the surface.
Why does my epoxy floor look dull after cleaning?
A hazy or dull look after cleaning is almost always caused by soap residue that wasn’t fully rinsed away. Make sure your final rinse is thorough. If dullness persists even after a good rinse, the topcoat may be worn from age or heavy use — in that case, a professional recoat can restore the original shine.
Can I use a regular mop instead of a microfiber mop?
You can, but microfiber is strongly recommended. Traditional string or cotton mops tend to push water around rather than absorbing it, and they can leave behind streaks. Microfiber is far more effective at picking up fine dust and leaving a clean, streak-free surface.
