Those white, hazy spots on your windows that won't come off with regular cleaning? They're likely hard water stains — mineral deposits left behind when water evaporates. Here's what Nanaimo homeowners should know.
What Causes Hard Water Stains?
- Sprinkler overspray: Irrigation water hitting windows is the most common cause
- Well water: Higher mineral content than municipal water
- Rain runoff: Water dripping from concrete, stucco, or brick carries minerals
- Pressure washing: Unfiltered water sprayed on windows during house washing
Why Household Cleaners Don't Work
Regular glass cleaners are designed for organic dirt, not mineral deposits. Hard water stains are essentially rock bonded to glass — they require acidic or abrasive treatment to remove.
Professional Hard Water Removal
Professional window cleaners use specialized compounds and techniques to remove hard water stains without scratching glass. The process may include:
- Assessment of stain severity
- Application of appropriate chemical treatment
- Careful scrubbing with non-abrasive pads
- Polishing to restore clarity
- Final cleaning to remove residue
Prevention Tips
- Adjust sprinkler heads to avoid windows
- Clean windows promptly after pressure washing nearby
- Consider water softening if you have a well
