Hard Water Stain Removal in Orange County
Orange County tap water is hard, and sprinklers that hit windows leave white mineral spots that a normal wash will not remove. Near the coast, salt spray adds its own film. Hard water stain removal uses glass-safe mineral removers and polishing pads. If spots are left for years they can etch the glass, and etching can only be reduced, not erased.

Cleaning only
Window, gutter, solar and exterior washing in California does not need a CSLB contractor license, only a local business license. Repairs, solar removal and paint-prep jobs are licensed work and only go to licensed partners.
Runoff compliant
Orange County storm water rules do not allow wash water to reach the curb, gutter or storm drain. Partners agree to contain and recover it.
Low-rise only
Homes and buildings from 1 to 3 stories. We do not route high-rise or rope-access window work.
Equipment rules
California requires new large gas pressure washers sold from model year 2028 to be zero-emission. Existing equipment stays legal to use.
Hard Water Stain Removal FAQ
Usually about $10 - $30 per window on top of regular window cleaning, depending on how heavy the spots are.
Fresh mineral spots usually come off. Spots left for years can etch the glass. Etching can be improved but not always removed.
Adjust sprinkler heads so they do not hit glass, water early in the morning, and clean the windows a few times a year so minerals never build up.
