How to Remove Water Stains from a Powder Coating

Powder coating is sprayed on a surface, then heated until the individual powder particles melt together. This process produces a surface that is hard and resistant to stains, but that does not mean that you will never have a problem. If you do experience problems with water stains on your powder-coated items, you need to use the right cleaner to get rid of them.

Instructions

      Spray a lime scale remover directly on the hard-water stains and calcium deposits that have accumulated on the powder-coated surface. You can find lime scale removers at home improvement warehouses, hardware stores and janitorial supply centers.

      Wait 15 minutes for the lime scale remover to work. Wipe the remaining lime scale remover away with a soft cloth.

      Rinse the powder-coated item with warm water. Use a scrubber brush to remove any remaining water stains. Continue to clean the water stains until no more remain.
