Is that honed? have you tried a marble polishing compound gently-I think that will knock it out-looks like the grout is hanging up in the porcelain-unsanded grout? or something fancier?On Mon, Mar 21, 2022 at 4:43 PM Blain Haeg <blain@goldstandardfloorcare.com> wrote:Customer had a new porcelain slab counter installed. When the backsplash was grouted, the cleanup left stains on the porcelain, probably from the dye in the grout. Traditional cleaning has no impact. Also, no luck with acetone or mineral spirits. Looking for ideas on what we might try to remove the discoloration.Blain Haeg
