  • Remove “salt stains” from carpets

    “Salt” stains are usually caused by calcium chloride and magnesium chloride, not sodium chloride, according to the Carpet and Rug Institute. Rock salt has small amounts of both of these salts imbedded in it. The problem comes with solubility. Patience and lots of rinse cycles are the key and sometimes calcium carbonate forms and this is fairly insoluble. Try to vacuum most of the dry residue off before using cool to warm water and a very small amount of carpet shampoo. Once the cleaning solution has been applied, allow time for it to dissolve the deposit. Blot, do not scrub, the spot. Sodium chloride is more soluble at lower temps than at higher ones. Then rinse with clear lukewarm water, blotting up the excess moisture and follow with another water rinse and blot dry. This should work. If not, try a cleaning mixture of 1/2 white vinegar to 1/2 lukewarm water, allow to stand 15 minutes and rinse with clear water.
