Is it really a stain or just dirt?

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. The pro uses 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.
