I have two rust colored stains on my bathroom vanity. I've tried baking soda & lemon juice, Mr. Clean Eraser, CLR, Lime away, Barkeeper's Friend, etc. with no success. Any other ideas on how to remove them?

Of note: These were already here when I purchased my home, so I do not know the cause.

  • Is that a porcelain enamel sink, or plastic? Looks more like a dye leaching into plasticizer than a rust stain to me. Jun 7 '13 at 18:56

I'd stick with CLR or vinegar : use plumber's putty to make a ring and make a small pool. Hydrogen peroxide would be another choice (not concurrently, with ANY of the other choices)

Its location suggests a leaky soap dispenser.

Solid surface materials can be sanded (starting at 220) and then up through the grits (320, 400, 600), finishing with auto body rubbing compound then polishing compound.

  • H2O2, or bleach will oxidize some dyes to colorless. Other dyes respond better to being reduced. For that, the Sodium hydrosulfite in Rit Color Remover could well suffice: hpd.nlm.nih.gov/cgi-bin/household/… I'd try both possibilities before getting out the sandpaper. Jun 7 '13 at 19:26

OK you have tried all of the right things. Now it's time to bring out the big guns...

The Works - Completely anti-green. Tons of hydrochloric acid in it - which helps break down rust.

SOS pads - You can't use these too much because they can take off the finish coat.

Wear some thick plastic gloves, turn on the fan, pour a little The Works on the rust, let it sit for 5-10 mins, scrub slowly with a lot of pressure with SOS pad.
