We begin with a condition check and small test area to dial in the safest, most effective method. A mineral-dissolving treatment softens deposits, then we lift remaining residues with clay or dedicated media. If faint rings or haze remain, a light machine polish refines the surface and restores clarity. Glass receives a targeted pass for perfect visibility, and we finish with a protective sealant so water sheets and beads off more cleanly. You’ll get simple aftercare tips like avoiding sun-dry rinses and topping protection regularly to help prevent spots from returning.
