Hard water stains on windows — what actually works
Well water and irrigation overspray are common out here. If a regular wash did not move it, you are not dealing with dirt.
January 28, 2026

Rural Uxbridge, Scugog, and Brock properties often sit on wells. Sprinklers and a dry summer bake minerals onto the south and west glass. Elbow grease smears them.
We look at a pane on the quote visit and tell you if it is surface film or etching. Surface film we can treat. Etching is in the glass — anyone who promises otherwise is selling hope.
What not to try
Vinegar helps with fresh spots and does almost nothing to baked summer overspray. Dry erasers can haze tempered glass. If the sprinkler arc hits the window, fix the head. Paying to restore the same elevation every August is a landscaping problem.
