Hard water stains on shower glass: renter-safe removal (no scratches)

Hard water leaves mineral deposits (often calcium/lime) that look like a cloudy film. In rentals, the goal is to remove buildup without scratching the glass or damaging finishes.

Human-proof tip: take a quick before/after photo in the same lighting and add it to the article. It’s a strong trust signal.

What to avoid (common damage)

Abrasive powders (can permanently haze glass).
Steel wool / scouring pads (scratches).
Razor blades unless you’re experienced and the glass is confirmed safe (risky in rentals).
Strong acids on natural stone (if your shower has stone/tile nearby).

Renter-safe methods (start here)

Method	Best for	How
Warm vinegar compress	Light to moderate buildup	Soak paper towels, apply 15–30 min, wipe, rinse
Citric acid solution	Moderate buildup	Dissolve in warm water, spray, dwell, wipe, rinse
Non-abrasive descaler	Stubborn spots	Patch test first, follow label, rinse thoroughly

Step-by-step (low-risk)

Rinse the glass with warm water to remove loose grit.
Apply vinegar compress (paper towels) to the cloudy areas.
Wait 15–30 minutes (don’t let it dry out).
Wipe with a microfiber cloth. If needed, repeat once.
Rinse thoroughly and dry with a clean cloth.

Prevention (2-minute routine)

Squeegee the glass after showers (30–60 seconds).
Keep a small spray bottle of diluted vinegar (weekly light spray + rinse).
Improve bathroom humidity control (see mold prevention checklist).
