How do I keep hard-water spots off shower glass?
Tahoe & Altitude · Answered by Lake Tahoe Glass, the CA shore’s glass shop.
The short answer
Squeegee after showers (the 20-second habit that does 80% of the work), ventilate, clean weekly with a vinegar-safe routine, and consider factory hydrophobic coatings when you buy new glass. Etched-in minerals may need professional attention or replacement.
The full picture
Mineral spotting is water evaporating and leaving its dissolved minerals behind — repeat daily for a few years and the deposits bond with the glass surface, eventually etching it. Prevention is genuinely easy: a squeegee within a minute of the last rinse removes the water before it can dry. Twenty seconds, most of the problem gone.
For maintenance, diluted white vinegar or a dedicated glass mineral cleaner weekly keeps early deposits from bonding (skip vinegar on natural stone surrounds). Once glass feels rough or looks permanently cloudy under bright light, the minerals have etched — polishing compounds can help mild cases, but heavily etched glass usually wants replacement.
Buying new shower glass? Order it with a factory hydrophobic coating (EnduroShield-class treatments) — water sheets off instead of beading, spots take far longer to form, and the squeegee habit gets easier to keep. We quote coated and uncoated so you see the actual difference in cost.

Why do dual-pane windows fog up so fast in Tahoe?
Altitude. Sealed units built near sea level arrive at 6,200+ feet with big pressure imbalance — the panes bow, the seals strain and fail early, moisture gets in and the desiccant saturates. The fix is a replacement unit built for elevation. Full answer →
What is high-altitude glass, and do I actually need it at Lake Tahoe?
It's insulated glass adjusted for elevation — pressure-equalized at manufacture or fitted with capillary tubes so the sealed unit isn't permanently stressed at 6,200+ feet. At lake elevation: yes, you want it. It's how we order. Full answer →
Can Tahoe cold snaps really crack a window on their own?
Yes — thermal stress cracks are real. Low winter sun heats the middle of a pane while the shaded edges stay frozen; the uneven expansion snaps the glass, usually starting as a clean crack from the edge. Annealed glass with a nicked edge is most at risk. Full answer →
