💧Water Spot Remover (Paint)

Water spot removers are mild acidic cleaners that dissolve the calcium and mineral deposits left when hard water dries on paint — those ring-shaped etchings you get after rain, sprinkler overspray, or letting a wash dry in the sun. Use one when a clay bar or quick detailer isn't pulling the spots out, before they etch deeper into the clearcoat. Work on a cool panel, one section at a time, and follow up with a wax or sealant — the acid strips whatever protection was there.
