CRL Water Spot Remover is specifically formulated for use by professional window cleaning contractors and glazing professionals. It is designed to remove any residue left on glass which may alter the optical clarity, and can not be cleaned using standard methods. CRL Water Spot Remover will make glass clear again if it has turned hazy due to caustic and corrosive air pollution, acid rain, auto exhaust, hard water deposits, corrosive cleaning materials, dust and dirt residues. It works by dissolving mineral deposits from the surface of the glass, and prevents their redeposit later. Because CRL Water Spot Remover is an acid-based product, it has the ability to dissolve deposits found in the rough pits and ridges of the glass surface, leaving it looking almost like new.
Stage I Corrosion is defined as glass with light corrosion, with little or no damage to the glass. Stage II Corrosion occurs when the deposits are no longer on the surface of the glass, but have started to break down the molecular structure of the glass, leaving an etched or white haze on the glass after the stain has been removed. CRL Water Spot Remover will not repair glass with Stage II Corrosion. Important Notes: This product is for use only by glazing professionals. It is not intended or recommended for consumer use, for use on automotive glass, or for use on the coated sides of chemically-treated glass including self-cleaning glass. Check label and Material Safety Data Sheet for any additional limitations and warnings.
