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. When using the right equipment and cleaners, you will help to ensure a clean and glossy surface for years to come. These top cleaning tips apply to polyurea, polyurethane, and polyaspartic garage floor coatings as well.
Though easy to maintain, there are some don’ts about cleaning epoxy garage floors that you need to be aware of. As a result, we will cover cleaners and solutions that you do not want to use. Some of these can leave a hazy film on the surface that attracts dirt and will make it slippery when it gets wet. There are even some cleaners that may de-gloss the shine or cause it to fade.
So let’s take a look at what cleaners to use, what not to use, and some recommended cleaning methods.
Epoxy floor cleaning and maintenance
As resilient as garage floors coatings are to dirt and stains, they do require some routine cleaning maintenance to keep their shine. If left unattended for long periods, some coatings can start to loose their gloss. This is due to the sanding effect that is caused from loose dirt and grime that gets caught up under shoes and tires. Once the gloss of a coating is gone, there is nothing you can do to bring it back short of applying a new top coat.
The first thing we suggest is getting yourself a quality 24” to 36” dust mop.
You can find these at your local home improvement centers or you can purchase the one that we recommend here from Amazon
.
You will find that a dust mop makes quick work of removing dust and loose dirt and will account for a large percentage of your epoxy floor cleaning duties.
Since dust and most dirt will 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 an anti-slip additive in the top coat.
If you have a floor coating with an aggressive anti-slip aggregate or you don’t care for dust mops for a particular reason, then a soft bristle push broom works well.
We like these here from Amazon.
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.
Recommended cleaning solutions and mops for epoxy floors
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. Of course, you can do it sooner if needed.
Listed below are our favorite mops and cleaning solutions that have proven to get the job done.
Mops
We have found that microfiber mops are one of the best for cleaning floor coatings. As with most floor mopping, frequent rinsing in the cleaning solution is the key for the best results.
Our absolute favorite is this one here from Amazon. It’s commercial quality and has an 18″ width which helps to cover more floor to get the job done faster.
You can also get this mop in a larger 24″ model if you have a very large floor. The only downside is that you loose a little bit of scrubbing pressure due to the larger footprint.
What’s nice about this mop is that it also comes with a microfiber dust mop pad for your routine cleaning maintenance. It’s like getting two mops in one!
Ammonia
The cleaning solution that works best for epoxy and other garage floor coatings is ammonia. Use ½ cup of ammonia to one gallon of hot water in a bucket.
Our favorite is Parson’s ammonia. You can find it here at Amazon.
Apply it using the microfiber mop. Be sure to pull the mop pad and rinse it frequently in the cleaning solution 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.
Simple Green
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 concentrated Simple Green to 8 parts water. A deck brush helps for scrubbing in this case. We like this lemon scented concentrate here.
You can mix it stronger if necessary, however, keep in mind that Simple Green can leave a film on the coating. It’s important to use a separate bucket of clean water and mop to rinse the floor as you go. You can also just rinse clean with a hose if you like.
Use a squeegee or clean push broom to push out any excess water if using a hose. The floor should dry fairly quickly after that.
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.
Do not use these cleaners on garage floor coatings
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.
I need to clean my garage floor it was painted years ago with a good two-part epoxy it has faded over the years but I really do not want to get into the cost of removing and redoing it so I want to give it good cleaning I have a mechanical buffer/cleaner should I use this, and if so what cleaner should I use?
Hello Paul. Cleaning will not bring back the color or gloss if that is your goal. Mechanical scrubbing or buffing of coatings is not recommended as it will effectively degloss the surface. A light scrub with a deck brush and degreaser is all that is required to clean the surface.
So I put Apoxsee on all my garage floors and I never figure out really an easy thing to use to get what gets on your hands off. Anyone have anything out there that’s worth a crap?
Hi Bryan. Epoxy and other coatings can be extremely difficult to remove from your skin if allowed to cure long enough. Acetone or MEK will work somewhat if you did not wait too long. After that, you may have to wait a week or two while skin cells shed in order for it to loosen up enough to clean off. This is why gloves are a must 🙂
I have a large epoxy covered floor in a grooming shop. We have cleaning crew that mops regularly, but it still has dirt. It’s a large area so I was thinking of using a mechanical floor cleaner. Any recommendations?
Hi Jonathan. We don’t recommend mechanical floor scrubbers for coatings. They are typically too aggressive and will degloss the finish.
Will ammonia work with water? What kind of mop?
Hi Andi. Yes, it will. We discuss this in the article as well as what type of mop to use.
My car dripped power steering fluid (or might have been transmission fluid ) and has left a stain. Can I use steam to remove it or if not, what?
Hi Jean. You can use steam as long as the point of contact does not exceed 140 degrees. Most coatings begin to soften at that temperature and can result in hazing or loss of gloss.
Have you any other suggestions for getting the stain out?
A light scrubbing with a degreaser is the first thing you should try if you have not done that already. If it’s a quality coating (not a single coat DIY store bought kit), a little bit of acetone or MEK lightly rubbed with a soft cloth will remove some stains as well.
How best to remove car tire marks on the epoxy / poly floor surface in our garage?
Hello Dean. There is paragraph in the article that discusses tire marks with a link to this article here.
I spilled rust remover onto the floor and it looks as though it has taken out the color from the epoxy flooring. What can I do to stain the floor back to its original color in that spot?
Thank you for the assistance!
Hi Sherri. If it caused the color to fade, then unfortunately there isn’t anything you can do. Epoxy cannot be color stained. Out of curiosity, was this a single coat home improvement store type of epoxy coating?
no, it was done by a pro – Garage envy
Can an epoxy garage floor be resealed? And what would you recommend? I would love to bring a little bit of the shine back to my floor. And cleaning is not doing it
Hi Vicky. Epoxy is already a sealer, so the floor is sealed if the coating is sound. If you want to bring the gloss back, it will require applying a new coat. If there is a clear coat on it, then it will require roughing up the surface and applying a new clear coat. If there is no clear coat, then you will need to apply a new color coat. We have an article here that discusses how it is done.
