Clear any vehicles out of the garage and keep the garage doors open.
Use your pressure washer to loosen and wash the salt stains away, directing water toward the garage doors. Pressure washers can shoot water much faster than standard hoses and consume less water. If you don't have a pressure washer you can try to use a standard hose, which can work for mild to moderate salt stains.
Use a stiff-bristled brush to scrub the salt stains and loosen them up. The water that the pressure washing leaves behind will help dissolve the stains.
Use your pressure washer again to clean away the salt that you loosened with your brush.
Continue to alternate between the pressure washing and scrubbing until the stains are gone.
Use a wet mop to soak up and remove water from the garage floor.
Use a leaf blower to evaporate any moisture left behind.
Things You Will Need
- Pressure washer
- Stiff-bristled brush
- Wet mop
- Leaf blower
- In the summertime, consider treating your garage floor with paint, stain or other moisture sealants, because this will make salt stains much easier to clean and prevent them from sinking into porous surfaces like concrete. Don't try to wash salt stains away when the temperature is below freezing or may drop below freezing.
