Hi Theresse,
I am so sorry about the stain on your beautiful backsplash.
I'm sure you will get lots of advice.
For now, I will post this link on making a poultice.
Fingers crossed!

Oh no! I'm so sorry this happened. Can you find out for sure what product they were using so you know what the stain is? It always helps to know what you are dealing with with any kind of stain removal. Do you have any leftover backsplash pieces you can practice removal techniques on?

You could try a clay bar to see if it removes the embedded stain. People use it to clean the grit and paint off of cars to help get a mirror finish. Again, it's something you should practice on a sample and not you backsplash to see if it helps, not hurts

On a positive note, the stain does point the way to your great electric choices :-)
Good luck!

"Any thoughts on how to remove this? "

Yes. Call the lead abatement company and tell them that they have a stain to remove from your brand new marble backsplash.

Do find out what it is. It'll probably come off. Marble is pretty stain-resistant. I suppose you tried a Magic Eraser type thing?

On the bright side, you need random stains to get that authentic vintage feel, right?

OT to Theresse,

Do you remember talking to my husband and me a month or so ago? Can you check your email connected to your GW account? Or call us over the weekend? We are in the hospital, but should be home by then. My DH's situation has changed and our experience may be useful for you and your DH to know about. Hope all is well.

And I hope you get that stain removed - I think it will be removable. So annoying!

So sorry about your stain! I will be watching to see how you are able to get it out... fingers crossed...

LOVE your marble tile and electric switches though!

Thank you everyone for the helpful responses!

First of all, Liriodendron: thank you for letting me know this scary news. I checked my hotmail acct. and couldn't find an email from you but I just wrote you from an account I use much more frequently. Our thoughts and prayers are with your husband and you. Please write back as soon as you can. Nothing new on our end, thank you. I hope everything's okay.

Francoise - that's a great link, thank you! I love this site - I just knew I'd great better responses than I probably would doing any extensive google search - haha.

Skydog - thanks for the clay bar info as well! The product they used was this strong-smelling red putty which most paint stores sell. They claim it's a better fillers than other re. possible lead paint underneath and having to sand over (or maybe it's particularly re. wet-sanding by hand that it's better for, i'm not sure). At any rate, I can easily get that, and I do have extra spare marble I can test it on. Great idea!

Clulessincolorado - oh, you're sweet. :) I do like the old fashioned push button look although I sometimes question whether a polished nickel might not have looked nicer than the ultra bright white. Black might look nice too. At first I thought an aged brass would clash too much with no other brass around in the room, but then I thought maybe the bronze look would do. Glad you liked the white though. It'll do for now - I've obviously got bigger fish to fry in that damned kitchen. Ha - fish to fry in the kitchen. That's not quite a pun, but almost!

Lazygardens - well I seem to have the most WONDERFUL luck with contractors...at this point I just assume do the research myself and try to fix it myself cause I no longer trust the guys that caused the damage. As it was, they were back to fix mistakes that were pretty ridiculous. It's amazing, my luck w/ contractors! I wasn't messing around this time so found them from the state lead control website! I was sure anyone they said were certified would be good and they of course seemed good but alas... it wasn't meant to be. Anyway long story short, I don't want them touching the marble again.

Fori - I agree and have my fingers crossed. The stain could, I suppose, be worse. Some marble's pink, right? ;) It's so annoying though, that this has happened. I'll be happier even if it only comes out a little more.

Autumn-butterfly - thank you! :)

I'll let you guys know what i end up figuring out/doing. For now I'm in high gear painting mode as I'm throwing a big baby shower on Saturday and am only painting the kitchen (with a friend's help) TONIGHT! Walls and ceiling tonight, cabinets and all trim tomorrow. VERY little time to dry! FYI (unrelated to the stain issue) - the cabinets and trim will be BM's Fieldstone gray - same color as the lowers for those of you who might remember (not keeping the uppers white - although I'll re-paint them white if I hate them in the gray-green color) and then the walls were a last-minute decision before the store closed (!) so are a hopefully safe BM Linen White. Wish me luck on this, too, please!
