are a PITA!!! Sorry, I am getting frustrated...
I am about to say the heck with it & buy 3 new toilets. I have tried everything.
Various commercial toilet bowl cleaners - Useless
C.L.R. - Useless
Hydrogen peroxide - Useless
Vinegar - Useless
Muriatic acid - Barely made a dent
Tomorrow I will drain the suckers & & try 1000 grit wet/dry sandpaper... GRRRRR....
