Here are two methods for removing stains caused by spilled red wine on unfinished wood—for example, on a butcher-block countertop.
1. Mix some Oxi-Clean with water to make a paste and put it on the affected area. Check after a few minutes to be sure it’s doing something. If so, leave it for a short time until the wine stain is removed.
2. Scrub the wood with a scouring powder, such as Ajax, that contains a little chlorine bleach.
If either of these methods leaves a lighter spot on the wood, apply the cleaning solution to the entire surface so it will be an even color.
