I am not sure if this topic is stored somewhere else.

I have a job to survey, the customer has  marble walls and floor in their bathroom that has stains on it from builders doing renovation work.

Some help please from a hard floor specialist, what products give the best results?

Cheers clinton

A good Alkaline hard surface cleaner, dont use an acidic cleaner. Marble being porous has absorbed the builders staining and may be impossible to get out, unless it is just sitting on top of a protective seal, or impregnator. Thorough flushing and extraction of detergent is essential.
