Cleaning an epoxy garage floor coating is not difficult at all. The ease of maintenance is, in fact, a basis for having a floor coating. You will want to keep the shine while being able to clean away all dust, spills, and other messes. Some cleaners can leave a film on the surface of your floor while others may cause the luster to fade. Here are some tips on what cleaners to use, which ones to stay away from, and some great techniques for keeping a beautiful garage floor for years to come.
*Please note that these tips apply to polyurethane top coats, and polyaspartic or polyurea coatings as well.

Epoxy Floor Cleaning and Maintenance
Getting a good quality 24” to 36” dust mop will be the place to begin. A dust mop will take care of 90% of your coated garage floor cleaning needs. You will only need to use the dust mop once a week (more if needed) to keep the floor clear of dust and dirt. With just a few minutes you will maintain a gorgeous floor without a lot of effort.
This method can be used on floors with a polymer anti-slip additive in the surface as well. If you have a more aggressive anti-slip aggregate such as aluminum oxide, a soft bristle push broom is the better choice.
Spot cleaning for spills and fluid leaks from cars are easily wiped up with a soft cloth. You can usually clean the area with a shot of Windex (without vinegar additive) if the spill has left a film.

In depth Cleaning
It is a good idea to give your epoxy floor a more in depth cleaning every 3 to 4 months, especially if there is a lot of traffic or dirt. The best tool for doing this is a good quality hard foam mop with a cleaning solution. Using a string mop can leave streaks and typically doesn’t clean as well.
A fantastic cleaning solution is a spray bottle with an 8:1 ratio of Simple Green and a bucket of hot water. Spray the Simple Green in sections on the floor and then scrub it with a damp foam mop. Dip the mop into the hot water to give the floor a rinse and you are finished. It’s that easy.
This method also works well for cleaning up films left behind from de-icing fluids and road salts that have dried on the surface. Just increase the strength of the Simple Green as needed to remove the film.
Another idea for regular cleaning is ½ cup of ammonia to a gallon of hot water in a bucket. Apply it using the foam mop being sure to rinse the mop frequently in the bucket of hot water to rid it of the dirty residue.
When using these methods, you can just let the floor air dry or wipe it dry with a clean towel.

Resistant Spots
For stubborn spots, we recommend using a stiff nylon brush to scrub the area along with a stronger solution of Simple Green, if necessary. Be careful of using a green scrub pad. These can work well, but depending on the quality of your epoxy coating, they can de-gloss the surface somewhat if you scrub too hard.
For rust stains or stubborn salt film, you might try using a 1:1 ratio of CLR and warm water. Apply it directly to the rust spot using a scrub brush or scrub pad and then rinse with cold clean water. Do not let it sit for more than a minute or two on the surface.

Not recommended
When cleaning your garage floor coating, do not use citrus cleaners or vinegar. These types of cleaners contain acids that can slowly decrease the shine of the finish of your epoxy over time.
Don’t use cleaners with soap in them. Soap can leave streak marks and a hazy film on the surface that reduces the gleam from the finish. It can also make the floor much more slippery when it gets wet.

As you can see, it is easy to maintain a beautiful epoxy garage floor. With these simple tips and methods you can be a pro with little effort.
