uba tuba stain

Good morning. I have an uba tuba counter which has an ash gray like stain in it. I tried peroxide, peroxide and vinegar, while it lifted it a bit, it did not remove it. I don't know what caused it. Any suggestions? Thank you.

 

Dear Marie:

 

“ ash gray like stain in it. ”

 

I never even heard of such a stain… Was it always there, of did it happen sometime afterwards?

Send me a couple of pictures so that I can try to figure out what this mysterious stain is all about.

In the meantime…
