How To Clean Garage Floor

We all know that the garage floors do not stay clean for long thanks to the cars, lawnmowers, and several other tools that make their way into them. However, despite garages being such high traffic spots in our homes, many times we do not include them in our regular home cleaning list and that usually makes the garage floor stains stubborn and harder to remove.

So, to maintain the garage floors, it is important that you frequently dust and sweep the floors and do a monthly deep cleanup. However, it is worth mentioning that the cleaning techniques will vary depending on the type of stains you are dealing with as well as the kind of garage floor you have.

We will be covering the details in this article, so if you want to know how you maintain your garage and keep the floors clean, keep scrolling below.

Concrete Garage Floors- How to Clean Them?

Concrete floors are good but they do not last forever. Oil and water can penetrate easily and lead to permanent marks. So, if you notice stains on your concrete garage floor, deal with them at your earliest. 

1. Empty the garage

The less the number of items inside the garage, the easier it will be to remove the stains. So, before you start cleaning, get rid of as many items as possible. Large items like cars, bikes, basins, boxes, and tools should be removed. You may leave items that will not interfere with your cleaning work. 

2. Protect the drywall

If you leave the drywall exposed, it will get damaged from water and lead to molds in the near future. To avoid that, it is recommended that you cover around 3 feet (from the floor) of it with a tarp. This will also help protect any outlets present on your garage floor. 

3. Get rid of the dust

Getting rid of all the superficial dust and debris is very important before using water. So, sweep the floors and remove as much debris as possible.

4. Use detergent to clean

A good quality detergent will be great for most stains. All you have to do is take some powdered detergent and apply it to the stain in a generous amount. Then after some time, dip a stiff brush in warm water and use it to scrub the spot. You may have to apply pressure to remove the stubborn marks. Once the stains are removed, get rid of the remaining detergent and let the surface dry.

5. Lemon juice and vinegar are great for rust stains

Rust stains are very common in garages thanks to the presence of so many metal objects. Rust is hard to remove but lemon juice and vinegar make things easier. So, if you are frustrated with rust stains, simply pour lemon juice or white vinegar on the concerned spots. Let it stay for 5 mins and then put some elbow grease. After that, scrub the spot with a stiff brush until the marks are gone. 

If the rust stains are extremely stubborn, then you can use muriatic acid. You need to dilute it with water (1 part of muriatic acid with 10 parts of water). Remember to wear gloves, face masks, and goggles while cleaning. This is because muriatic acid is highly acidic and may cause burns on the skin. The strong fumes are also hazardous. 

6. Treat oil stains with cat litter

It may sound weird but if you want to avoid using chemicals, you can use cat litter to treat oil stains on your garage floor. They are highly absorbent and can remove stubborn oil marks.

You will need clay-based litter for it. Spread some over the stain in a generous amount and let it stay nightlong. In the morning get rid of the litter. You may have to repeat the process for a few days to get the desired result. 

7. Trisodium phosphate is good for paint stains

TSP is great for removing paint marks. At first, you need to scrape off the loose paint using a putty knife and sweep the spot around the mark. Then mix TSP with water and pour the mixture over the stain. After some time, scrub the spot to remove the remaining paint marks. For tougher paint stains, using a good quality commercial paint stripper is suggested. 

However, in both cases, wear gloves and make sure the garage is well ventilated. 

8. Deep clean if required

Sometimes, deep cleaning is the only solution to getting rid of the stains. 

  • Choose a product to clean the space. Normal laundry detergent or any degreasing product will work. Mix your preferred ingredient with warm water and pour on the stains.
  • Let it sit for around 10 mins and then using a broom, scrub the floor. During scrubbing, try to push the water and soap out of the garage. 
  • After that, use a garden hose, rinse the floor and let it dry.
  • If the garage floors are very grimy, going for a power wash is highly recommended. All you have to do is apply the cleaning mixture, let it sit for 20 mins, and then spray the floor with a power wash. Start from the back of the garage and move outward. The water should be drained out properly at the end. 

A word of advice

The above-mentioned methods are great for concrete floor stains but if your garage is made of epoxy, you should not use vinegar, citrus (orange lemon, grapefruit), or soap-based cleaners. Since epoxy floors do not stain much, it is better if you go for weekly sweeping using a dust mop. As far as washing it is concerned, do it on a monthly basis using water, ammonia, and a sponge mop. Simply mix ½ cup of ammonia with 1 gallon of water. Then dip the mop in it, squeeze out the excess solution, and mop the floor. Wipe the floor dry with a clean old cloth or use a floor squeegee. 


A little maintenance goes a long way. So, make your garage floors long-lasting by time-to-time cleaning.
