Restoring a Butcher-Block Countertop
When wood counters lose their good looks, here’s how to make them beautiful again, and keep them looking that way
Bleach Mildew Stains
Stir a teaspoon of powdered oxygen bleach (sodium percarbonate) into a cup of hot water until it dissolves. Wearing a nitrile glove, dip a stiff, nylon-bristle scrub brush into the solution and scrub the wood for a couple of minutes. Redip as needed to keep the surface wet. The mix will foam slightly, then subside.
Wait 10 minutes for the bleach to work, then rinse thoroughly with a sponge and cool water. The wood will lighten as it dries, but if it’s still stained, mix up a new batch of bleach and repeat the scrubbing process.
