It is part of the stuff that holds the synthetic "rubber" together. This acid can accelerate the wear and tear on your contacts and may lead to premature corrosion. Also, most alcohol from the drug store is "OK," but make sure you get a bottle that is only isopropyl alcohol and water; the higher the %alcohol, the better. Some manufacturers put in a dab of glycerine to help prevent the drying of the skin, but this leaves a film on the contacts and prevents proper drying of the alcohol after cleaning. Kirk A.
