Yes, there are plenty of hard water spot removers on the market. Some work decently and others - not so much. The problem with these products is: The ingredients these products use to remove calcium and other minerals, leaves paint surfaces looking Dull and Hazy. Fire Water is unique, in the fact that it removes even the most stubborn water spots. However, as it is wiped off the surface - the infused Si02 and paint conditioners leave behind an incredibly slick and Hydrophobic shine, which actually helps prevent future hard water from etching into paint.Hard water is a terribly destructive element, left behind from sprinklers, Acid rain, and a multitude of other sources. If left on the surface of paint for too long, hard water will etch its way into the surface and cause permanent damage. Fire Water will dissolve and remove the deposits left by hard water, leaving an incredible shine.
