Hard Water Staining Removal Tools

Hard Water Staining/ Mineral Staining
Damage Category: 1
Approx. Time/Sq. Ft.: 3 – 5 minutes

Hard Water Staining is a subtle yet persistent issue that arises when dissolved minerals in water achieve prolonged contact with glass surfaces. This prolonged exposure, particularly at certain concentrations, leads to the encapsulation of the underlying glass by these deposits. As a result, a robust chemical bonding occurs between the trace minerals within the glass and the residual dissolved minerals on its surface.

The hallmark of Hard Water staining is its appearance as a darker shadow or “stain” on the glass surface, which becomes evident after the surface deposits have been removed. This staining subtly permeates the outer layer of the glass, marking a change in its visual clarity. However, in cases of light staining, technicians can still observe areas of clear, unstained glass amidst the spots of deposit. This distinguishing feature is key to identifying the extent of the staining and formulating an appropriate restoration strategy. Addressing light hard water staining involves techniques that target both the removal of surface deposits and the mitigation of the underlying stains, to restore the glass to its original clarity.

Hard Water Staining is easily removed using GlassRenu’s Cutting Compound, Foam Finishing Disks, Polishing Compound, and Polishing Felts.
