I have used hand soap dispensers on my porcelain bathroom sinks. Unfortunately, they have left yellow circles/rings on the sinks now. I have tried many things, but I just can't find a solution to remove these stains. Please help. My bathrooms are only 3 years old. Thanks.
I have the same problem and I use baking soda with water vinegar made into a paste. Mix it, let it set for 10 min, and rub with a cloth. Works for me. Good Luck.
If the stains are on the sink itself like my stains from soap dispensers are try using dishwasher gel. Put some on the area, with a rag rub it in, let it sit a bit and then rub and rinse off. This is all I ever use to clean my sinks and tub after wondering one day why the side of the sink the dishwasher drained on was always so clean. Sadly, I no longer have the dishwasher, but I do have my gel to clean with. I use a store brand, but any kind should work.
