Carrera marble stain caused by plumbers putty
Hello. Wife and I recently had 2 bathrooms redone that have carrera marble in various spots. Unfortunately, the plumber left plumbers putty when installing the fixtures etc. and that has caused a number of dark rings in the marble. We simply had them replace tiles in a shower, but we also have a stain on a marble countertop. The marble person from whom we bought the countertop is telling our general contractor that he is reluctant to use a poultice to remove the stain because the poultice itself may leave a stain on the light colored marble. Instead, they are trying to use some type of acid(?) and then will repolish the marble. Everything I read however, says poultice is the way to go. Any thoughts on this or advice??? Thanks.
Also, I'm new to this forum, should I have posted on the "Cleaning" message board? Thanks
