How to remove paint stains off of Slate Tiles?

QUESTION

I used paint stripper to get paint off from slate tiles. It has now left big white patches on the slate. How can the tile colour be restored?

ANSWER

ANSWER - Slate is a very dense stone, so I would not expect it to have a deep stain.  I would not expect the stripper to cause the white staining.  I would initially assume that you did not remove all of the paint.  I would test it in an inconspicuous spot by adding more paint stripper on a portion of the white stain.  Let it sit awhile per the product directions.  Use a stiff scrub brush to agitate and remove the white stain.  Beware not to scratch the slate.  After cleaning the slate, rinse the tile per the stripper instructions to remove any remnants of the stripper.
