How to Clean Salt Stains From Garage Floors | eHow.com
Cold climates often leads to the accumulation of road salt and sand on a vehicle. When vehicles with salt-encrusted tires are parked in a garage, it is likely that salt will end up staining the floor as the moisture from the tires and vehicles drips and dries. Salt is soluble in water, making salt deposits easier to remove than motor oil stains.
Loosen and wash the salt stains away w/strong stream of directed water.
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 a wet mop to soak up and remove water from the garage floor.
Use a leaf blower to evaporate any moisture left behind.
PREVENT STAINS FROM SALT AND OTHER DAMAGES:
Over time, the concrete becomes stained and cracked from wear. Applying a sealant to your garage floor can make an old floor look like new and help prevent a new garage floor from becoming damaged. There are several types of sealants available, such as epoxy resin, acrylic and urethane. Epoxy and urethane last longer than acrylic, but acrylic is more resistant to fading.
You can use a large fan to help the sealant dry faster. You need to reseal your concrete garage floor every few years.
