How do I remove rust stains from formica countertop?

Shirley, oh boy! Have you tried a powder cleaners or manic sponge to get rid of the stains. Maybe bleach will work.

I used to try everything including lemon and baking soda paste to bleach it without ruining it.

Have you tried CLR?

TR Y WD40

Bar Keepers Friend will work and not discolor the countertop like any bleach product will.

WD40

Have you tried Brillo or bleach on a sponge and let it soak for a couple of hours cut the sponge small to fit over rust only

Hi Shirley. I'm Cindy. You could mix baking soda with just enough water to form a thick paste. Put this paste on the rust stain. Then lay a wet paper towel over the paste to keep it moist. Let it set 15 or 20 minutes. Then wipe it all up. Repeat if necessary. Good luck Shirley.
