What is the best way to remove a dark (red) wood stain that has penetrated a concrete slab.
I was refinishing a 2nd floor wood deck the other day, and accidentally dripped red tinted wood stain on the concrete slab below. Any tips on removing stain without bleaching? Any advice is appreciated.

Depends on the nature of the colorant. You might try oxalic acid (wood bleach).
vinegar.
no, MEK will do it, so will rock salt next winter.
