Default Carpenters/Granitetop/Plumber

Assistance please: have a granite top in the bath, and now have water stains (highlighted) around the hardware. I have checked and there are no water stains underneath. What are my options?
  • Remove faucets and allows to dry? Is water wicking through the cut-out? If that eliminates the staining then waterseal and reinstall hardware?
  • Remove faucets and take a heat gun to it?
  • Replace entire countertop?
Thanks for any inputs

Are the stains water or sealant that is not granite friendly?

We have that exact same granite and it has to have sealer applied about every 8 months or it starts looking like that. You can tell when it needs sealed because when you run a cloth over it to wipe it down it doesn't feel smooth.

Try putting some baking soda on the spots and leave overnight see if that doesn't remove it.

None. The stains may be from an oil based bedding the plumbers used to use. Try a poultice(sp)...powder to draw the oil out.

I'm in the GC business. How old is the top?

You may want to pull the supplies and make sure the plumber used teflon tape thread sealant and not pipe dope. Pipe dope has oils in it that will leach into granite and marble and leave similar stains.

Countertop is 10 1/2 years old. Teflon tape was used, thanks.

If the plumber used putty under the faucets the oil will leach out into the granite. I do not think there is anything that will remove the stain. I learned this the hard way

Granite will soak up oils????

Yes. On the unsealed parts. Where the holes were cored for the faucets the oil will leach right in.
Over the years at my computer desk (I have not been religious about sealing) the oils from my arms have darkened the granite.

Plumber used putty instead of silicone... a big no-no for us plumbers.

was in the business for 18+ years. Take a butane hand torch and start heating up the outside of the stain. If it is water it will quickly disperse. If it is from plumbers putty, the heat will break the oil up to dissipate oil in the stone. It looks like water stains honestly where it has run to the edge of the cutout. If it was putty, it will only be around the handles....unless the plumber smeared it all over the bottom of the stone..
