Has anyone had any luck removing the dyed black mulch stain from the pavement? Had a customer have their mulch delivered wet, and left a black stain on the concrete. Now they want that stain removed. Any luck??? Any Help??

I used bleach and a power washer. I sprayed the bleach on the stain let it soak then sprayed it again, then used my pressure washer to wash away the bleach and spray away the dye. I have also used this method to get rid of oil stains too, but I had to do a little scrubbing with a wire brush.
If you have it try Spray Nine, we use on sealcoating mistakes on concrete and what not.
