Hello all:

 

Again, thanks in advance for any help provided. Responses are always a help. Latest issue, custy has "dark granite", I have not seen it yet. Cleaned kitchen drain with Sulfuric acid, wiped up the mess with a rag and then set rag on granite counter. Says it is eating the granite , whitish. I believe him but is there anything that can be done. Cannot see him until Saturday so was looking for some help. I know hydrofluoric acid will cause problems but then what to do about it. Can it be repaired through face polishing?

 

thanks
