No matter how hard you try, some of that snow that’s on the bottom of your shoe is going to make it inside, and with it often comes the ice melt compound you’ve put down on the steps and walkways. Ice melt compound residue is unsightly on hard surface floors. On carpets, you may not see it, but the damage can be even worse.
The most commonly used melt compound is calcium chloride in small white pellets. This chemical pulls moisture from the air and leaves a moist, oily film that attracts dirt like glue.
To clean it from hard surface floor, use a light cleaner. But don’t wet mop it, because the mop may simply spread the residue around the floor. For the best results, just leave those shoes at the door.
