Mix a cleaning solution. Since chemical cleaners will not affect most epoxy floors, you can use most any household cleaner to wash the floors. Mix the cleaner with water to create the solution. The ratio of water to cleaner can vary. Add more cleaner if your garage floor is very dirty or if you haven't cleaned it in a while.
Use a soft bristle scrub brush to thoroughly scrub your garage floors with the cleaning solution you created. For areas with very stubborn dirt, spray the cleaner directly onto the area and then scrub with the scrub brush.
Rinse the entire floor with clean water to remove the residue left behind by the cleaner and the dirt you've scrubbed off the epoxy floor.
Rinse the floor a second time to ensure there is no remaining residue.
Use a wet/dry shop vac to remove all of the liquid and dry your garage floor. If you don't have a shop vac, use a squeegee and push the water into a drain in your garage.
Things You Will Need
- Soft bristle scrub brush
- Wet/dry shop vac or squeegee
- If the cleaner you're using doesn't seem to work well, switch to a stronger cleaner. Also, if your garage floor is greasy, such as with motor oil, choose a cleaner designed for cleaning grease stains.
