5 Ways to Remove Car Stains from Your Garage Floor

Garages are an incredibly convenient home feature. They protect your car from the elements, and many people use their garages for additional storage. However, floor stains are an all too common issue. Even if your car is in perfect working order, chances are it will leave a stain on your concrete floor at one point or another. These stains can be unsightly and strong-smelling — especially if they’re chemical stains. However, stains aren’t impossible to get out. We’ve listed the top five stain-removing strategies that’ll leave your garage looking better than ever.

Cat Litter

Cat litter is one of the best substances for getting greasy stains up. Highly absorbent and odor-free, cat litter will make getting stains out of your garage floor so much easier. Pour a liberal amount of litter onto the stain you want to remove and grind it into the surface well. Let it sit for a few hours (or a whole day for really tough stains), then sweep away using a stiff-bristled brush. Most of your stain should be gone!

You can also use saw dust if you prefer. If the grease has left a lasting stain, the next few tips should help get that up.


Best known for its lubricating properties, WD-40 is also great at getting tough oil stains out of concrete. It makes the mess far easier to sweep up. Simply apply WD-40 liberally to the stain and let it stand. Then, using a hose or a stiff-bristled brush, remove the WD-40 either by washing it away with high pressure from the hose or by scrubbing.

Concrete Cleaner

Concrete cleaner can be extremely strong-smelling, but if your garage is plagued by a stain that just won’t quit, concrete cleaner may be your best option. You’ll want to determine the severity of your stain before buying cleaning products. Using a heavy-duty cleaner unnecessarily can end up damaging your concrete by changing its color. However, if your garage floor is already in trouble due to a massive, deep stain, you may decide that the risk of discoloration isn’t a big deal.

Acid and Power Wash

This solution is best for garage owners who are accustomed to working with chemicals and chemical storage. Muriatric acid is one of the best ways to get stains out of a garage floor, especially when used in conjunction with a power washer. You’ll want the power washer to be set to at least 1200 PSI. After applying the acid and blasting it away with the washer, sprinkle some baking soda on the area to neutralize the acid.


It sounds ridiculous, but Kool-Aid does an excellent job of removing nasty rust stains from your concrete garage floor. Be sure to get the unsweetened lemonade kind, mix it up with hot water, and scrub with a stiff-bristled brush. The rust stain should lift with minimal effort!

Each of these methods will help you get a spotless garage floor! After cleaning, it’s a good idea to either stain or paint your garage floor to seal it, which will lead to fewer stains in the future.
