How to Remove Oil and Grease Stains from Concrete Garage Floors

In a garage, there will inevitably be the occasional oil or grease stain. Fluids may leak from vehicles, lawnmowers, and other outdoor power equipment. When using tools, you also run the risk of spilling a few drops of oil. To prevent sliding on new oil, trailing it into the home, or creating a tenacious stain, it is essential to attempt to wipe up these spills as soon as possible.

Cat litter or sawdust can be used to soak up new spills of grease or oil. After leaving the litter or sawdust in the mess for approximately a day, sweep it up and properly dispose of it.

After you have finished sweeping, apply laundry detergent or dry dish soap to the stain. Give it 45 minutes to sit. After that, apply water to the area and scrub with a nylon-bristle brush to avoid scratching the concrete. Rewash after letting the soap soak for ten to fifteen minutes. After cleaning, rinse with a power jet wand, diluting the soapy water, and directing it away from the garage.

Older stains are harder to get rid of. You may either carry out the cleaning procedure many times or purchase a degreasing solution from a home improvement or building supply store. Even with these treatments, you might need to use them and scrape at the spots numerous times.
