Hard water etching is an advanced form of glass deterioration that progresses from persistent hard water staining, especially in areas with high levels of dissolved solids. This occurs when dissolved minerals bond with trace minerals and oxides on the glass surface, leading to active erosion and structural changes.
While often resulting from long-term neglect, extremely hard water can cause etching within 12-18 months. This type of damage is challenging to restore because it involves not only removing surface discoloration but also repairing the physical alterations to restore the glass’s original clarity and integrity.
Hard Water Etching is easily removed using GlassRenu’s Cutting Compound, Foam Finishing Disks, Polishing Compound, and Polishing Felts.
