How to Clean and Maintain your Epoxy Garage Floor

Learning how to clean an epoxy garage floor coating isn’t hard. In fact, one of the primary reasons for having a floor coating is for the ease of maintenance. There are some basic cleaning tips for epoxy floors that you should be aware of, that will help ensure a nice clean surface for years to come. These cleaning tips are the same for polyurea, polyurethane, and polyaspartic garage floor coatings as well.

As resilient as garage floors coatings are to dirt and stains, they do require some cleaning maintenance to keep their shine. If not, some coatings can start to lose their gloss due to the sanding effect of the loose dirt and grime that gets caught up under shoes and tires.

Another issue to be aware of is that some cleaners can leave a film on the surface while others may de-gloss the shine or cause it to fade. So let’s take a look at what cleaners to use and what not to use, as well as some recommended cleaning methods.


The first thing we recommend is getting yourself a quality 24” to 36” dust mop. You can find these at your local home improvement centers or you can purchase them for a low price from Amazon. You will find that a dust mop will provide for 90% of your epoxy floor cleaning duties.

Since dust and dirt do not stick to the floor, just use the dust mop once a week (or sooner if needed) to keep the floor clean. It only takes a few minutes and you are done. They even work well for floors that have a polymer anti-slip additive in the surface.

If you have a floor coating with an aggressive anti-slip aggregate such as aluminum oxide or you don’t care for dust mops for a particular reason, then a soft bristle push broom makes for a great choice as well.

For garage floor coatings with contraction joints or saw cuts in the floor, vacuum them out monthly or use a broom to sweep them clean of debris.

Spot cleaning for spills or fluid leaks from cars can easily be wiped up with a paper towel, soft cloth, or a clean rag. A shot of Windex works wonders if the spill has left a film.


For epoxy garage floor coatings that see a lot of traffic and dirt, it’s a good idea to give your floor a good cleaning once every 3 or 4 months. The best cleaning tools for this is a good quality hard foam mop or microfiber mop.


Our favorite cleaning solution that works well for regular floor cleaning is ½ cup of ammonia to a gallon of hot water in a bucket. Apply it using the foam or microfiber mop. Be sure to rinse the mop frequently in the bucket of hot water to rid it of the debris it picks up. This even works well for floors that have salt film and residue. You really shouldn’t need anything stronger than this for most jobs.

Windex is another solution that will give you a little bit more cleaning power if it’s needed. Mix a ratio of 1 part Windex to 3 parts water. The chemicals in Windex will not leave a film on the coating and do a good job of cutting through residue.

For spot cleaning any stubborn dirt that you encounter, a soft scrub pad can be used. Just don’t scrub too hard or you may degloss the surface.

If for some reason you have some serious cleaning to do, Simple Green is a product that will work well at cleaning up grease and other grime. This really shouldn’t be needed unless you have a cleaning disaster on your hands or a worn floor of lower quality epoxy that has many scratches allowing dirt to get embedded.

Start with a solution of 1 part Simple Green to 8 parts water. A deck brush helps for scrubbing in this case. You can mix it stronger if necessary, however, keep in mind that Simple Green can leave a film on the coating. The key is to use a separate bucket of clean water and mop to rinse the floor as you go.

When using any of these methods you can just let the floor air dry. You can also wipe it down with a lint free towel if you prefer.

Marks left by tires can be the toughest to remove if not cleaned regularly. You can read more about removing tire marks in a separate article here.

For rust stains, we recommend using a 1:1 ratio of CLR and warm water. Apply it directly to the rust spot using a scrub brush or soft scrub pad and then rinse with cold clean water. Do not let it sit for more than a minute or two on the surface.


When cleaning your garage floor coating, do not use citrus cleaners or vinegar. These types of cleaners contain acids that can slowly degloss the finish of epoxy and other floor coatings over time.

Don’t use cleaners with soap in them as well. Soap can leave streak marks and a hazy film on the surface that impedes the shine of the finish. The soapy film can also make the floor much more slippery when it gets wet.

Cleaning an epoxy garage floor coating should be easy. Just use these cleaning tips and methods for your quick and easy floor coating maintenance. Doing so will help to maintain a cleaner looking floor that will hold its gloss and finish for a longer period of time.
