So yeha i live with my family in college, and its my duty to clean the bathrooms, been doing it for a long time but ive noticed these ugly brown spots and i cant seem to get rid of them. They are only on the sink and on the flat surface not the bowl where the water comes out. I've tried cleaning it with comet spray, and also CLR and bleach.....i dont know if its mold that can be removed or what, so whenever i clean it never looks like its clean because of these yellow/ light brown spots and my dad who fixes everything in the house doesnt know what to to either.
try nail polish remover. but only on the tile! i've used nail polish remover to get wax and other impossible junk off my bathroom counters.
I have no what they are, but I managed to get rid of hair dye from my daughter's vanity so you might like to try this. Soak a makeup remover pad with neat bleach and sit it on the spot/s. Leave for a day or so, re dampening as necessary. It took aver 24 hrs, but the dye stain was gone and there was no dicolouration where it had been. Good luck.
If your sink is imitation marble, your stuck with them. You need to be real careful of what you use on it if it is ,as allot of chemicals will start to melt that making a worse mess. If it is a Porcelain sink, (what the toilet is made from) use a pumice stone on it. That is a volcanic rock used to clean many things such as tile, toilets. It doesn't scratch the surface but does remove stains you never thought would come out. Buy one at Lowe's Hardware or any pool supply. Pretty cheap too. Only a couple of bucks.
