I think the acid that is suggested should be Muriatic not Hydrochloric. I've always used Muriatic. I sure would expect some frame etching though. I like the soaked rag idea - good one! I would try to use a putty knife or razor blade to scrape off as much as possible before dropping acid. But the best of all is to get the culprits to deal with it!
