Cleans gunk off shower stalls, easily

It makes cleaning old shower stalls a breeze. But you have to be careful and wear gloves of course. Also, open a window before you start using it so you have proper ventilation. Now there's no need to try to endlessly scrub away stubborn gunk. Muriatic acid is the way to go when you have tough cleaning jobs.
