Cleaning and Maintenance For Your Garage Floor Coating

One of the primary reasons for having a floor coating is for the ease of maintenance. There are some basic cleaning tips for garage floors to help insure a nice clean surface for years to come. These cleaning tips are the same for epoxy, polyurea, polyurethane, and polyaspartic garage floor coatings.

Some Maintenance Required

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 loose their gloss due to the sanding effect of the loose dirt and grime that gets caught up under shoes and tires.

Some cleaners can leave a film on the surface while others may de-gloss the shine or cause it to fade. We will examine some recommended cleaning methods.


The first thing we recommend is to get a quality 24” to 36” dust mop. You can find these at local home improvement centers or you can purchase them from Amazon. You will find that a dust mop will provide for 90% of your garage floor cleaning duties. Use the dust mop once a week (or sooner if needed) to keep the floor clean. They even work well for floors that have a polymer anti-slip additive in the surface.

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.

Heavy Duty Cleaning

For 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. Though some people swear by them, we are not the biggest fan of string mops. They just don’t scrub very well and have a tendency to leave streaks on glossy finishes. Our cleaning solution recommendations:

  • ½ cup of ammonia to a gallon of hot water in a bucket for regular floor cleaning. Apply it using the foam or microfiber mop, being sure to rinse the mop frequently. 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. 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.

  • 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.


  • Citrus cleaners or vinegar. These types of cleaners contain acids that can slowly degloss the finish of epoxy and other floor coatings over time.

  • Cleaners with soap. 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 your 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.
