The most common stains are removed with acid cleaners. In the 1940's it was Sani-Flush. That was sodium acid sulphate. More recently the products all were hydrochloric acid based and those are my favorites. I usually use Lysol toilet bowl cleaner I get at Costco. Products like Clorox toilet bowl cleaner are caustic and rely on oxidation of chlorine bleach to discolor stains and the detergent action of caustic to wash the surface. I would suggest that those of you using pumice, Zud, sandpaper, or other abrasive cleaners try rubbing it on the outide of a window or drinking glass and try looking through it. You will see that there is fine haze there. I tried a magic eraser and ruined the glass on a sliding back door that way.

I always have a large supply of elbow grease on hand for everything BUT the toilet... I hate sticking my hand in it... lol For really tough stains I use The Works bowl cleaner... I dump a bucket of cold water in the bowl to 'push' most of the water out and squirt in a good amount of cleaner, swish it around and let it sit over night then flush it all away in the morning... The rest of the time I use either bleach or distilled vinegar... The upstairs bathroom gets little use and there's heat vent next to the toilet and in the winter I some times get a ring of mold... I just pour in some bleach and that takes care of it... As for the vinegar, I use that once a month in all my drains, I pour a cup in every sink and toilet and let it sit over night... I use about a quart in the floor drains too... It cuts the grease and mineral deposits, it even deodorizes, and it's cheap... LOL Rita

Clorox will not harm sanigloss. Any disposable brush that won't scratch the finish will be fine. I usually use Clorox and leave it there for at least 10 minutes in all the toilets, put on rubber gloves and use either wads of paper towels or inexpensive sponges. They allow you to get under the rim and everywhere else and the gloves prevent you from getting wet. If you have horrible water that leaves bad stains and Clorox won't work, use CLR. But if you are just cleaning to disinfect pour in a little clorox and swish it with a disposable brush. Greg

How fun!! I do it the old fashioned way. Lock 2 ferrets in the bathroom while cleaning their cage. Leave toilet seat up, leave xtra tp rolls in the cabinet. Ferrets in their boredom will get the xtra tp from the cabinet, put it in the toilet, and scrub the bowl with all the tp lumps that they peel off. lol Thanks for the smiles!
