blue water staining - TilersForums.com

I'm assuming the stain is soaked in them? So you may only now be able to prevent it from getting worse with a sealer that isn't impregnating? (Total guess lol)

Can you remember what the substrate was and what adhesive would have been used?

a plumber told me it was the copper and flux reaction. I'm sure Lithofin do something but not sure if it's ok for marble.
haven't see the extent of the problem, may be only staining the white grout.

Hi all, back off hols, I would try firstly a mild alkaline generals tone cleaner If you have one, dilute as instructed, test with awhile pad

you could also try a midew product, us hg ltp do one this can often take an organic stain away, need to test , or if an oxide, a NON ACIDIC ( we have rust ex) rust remover may be a possibility . May be a problem on polished

I always tell customer .stone of any type is a live product .it needs care and continual protection .look after it .how can you be going back a year after finishing .

Could it be some dodgy shampoo or similar....

Hair dye or body tanning

Tell them to stop the smurf conventions .and washing dye of in shower

Most stains in marble are actually corrosion .you need to find out what .they are doing in that area before you treat and rectify it .you can make it worse if not done right .it can be problem with water .or acids or alkaline used near it
