i was helping do some spring cleanup at a b&b
and their white porcelain kitchen sink had all brown stains in it. it's their dishwashing sink.
after trying baking soda which worked a little, i wasn't satisfied with how it looked. since this works on porcelain mugs, i decided to try dishwasher detergent. it worked beautifully! i squirted in a nice coating of that thick gel and worked it all around, sides too, left it on a few minutes then rinsed it all away. i noticed one of the ingredients is chlorine bleach, so rinse thoroughly if you do this. the innkeeper was so happy ... i asked if she wanted me to try cleaning an old porcelain tub ... it's a clawfoot and they were considering refinishing. this worked great, too. i don't know if it's too caustic to use several times, but it really brought back that tub. just thought i'd share.
