We have had a lot of  different sales people come in to our shop trying to sell us water spot removers over the forty plus years we have been in business and there are quite a few products that are strong chemicals and should take great care in using. We have and sell a all natural none toxic cleaner that is the best in my opinion for home use it’s called “A-MAZ” Water Stain Remover. Removes hard water spots, mineral deposits, alkali, lime scale, calcium oxidation, rust rings, mold/mildew, soap scum and more – For use on bathtub enclosures, tile/grout, sinks, toilets, fixtures, stove tops, ovens, grills, patio/pool areas, Corian countertops, copperware, brass, boats, RVs and more – No harsh chemicals

After cleaning your shower or auto glass we recommend Aquapel Glass Treatment because unlike other commercial rain repellents that can wash away in a matter of hours, Aquapel Glass Treatment forms a chemical bond with glass that increases water repellency, causing it to bead and shed to help keep them cleaner longer. Also, use on glass shower doors help keep hard water marks off and help fight mildew and soap scum.
