We had a shindig here the other night and someone puked on our rear legs deck and no one notice it until the the next afternoon and it be all dried out. I tried cleaning it up near both car wash soap and with white vinegar but within is still a big stain that looks like a shadow on the deck. The deck is redwood beside brown paint over it. Please help.

One might try the home variety pressure washer,beyond that you may finishing up repainting that area.Other thoughts would be approaching pinesol with a tad of bleach and scrub pad/brush.

Good Luck
