While ice melter residues are common on sidewalks and parking lots, tracking of ice melters indoors can also result in residues on floors and carpets.
When sodium or potassium chlorides are applied, they melt into the snow to form a brine solution. If the concentration is great enough, a dry white residue may be left after evaporation.
These residues are water-soluble and are usually easy to remove. Calcium chloride can also leave a residue on floors. To avoid residue build-up and protect interior surface areas, neutralizing agents and floor conditioners can be used.
On carpeted surfaces, shampooing will remove residues should vacuuming not provide sufficient cleaning action.
Avoid the use of pure traction aids such as sand, which will not melt ice and can scuff polished surfaces.
Residues from ice melters are greatly increased with overapplication.
Using a coloured ice melter as well as proper application equipment will help to prevent overapplication.
