Is it really a stain or just dirt?
Hard water etching is calcium and magnesium chemically bonded to the glass. Regular cleaning makes it cleaner but the etching remains. The test: clean the panel with DI water and look at it backlit. If there's still a haze or rainbow shimmer, that's etching.
Won't acid damage my panels?
Concentrated acid would. We use a dilute, panel-safe formulation that works in the 2-5 minute contact range, then a full DI rinse to neutralize. Manufacturers test panels against this method during certification.
