Cleaning wooden bowls can be a delicate matter. Address stains quickly—your best bet is to wash it immediately after you use it before the stain gets too saturated into the wood. Prolonged exposure to water will damage the wood, so never soak it or put it in the dishwasher! Instead, wash it by hand using warm water, a few drops of dish soap, and a soft sponge. Then, let it air dry completely.
