What are the best practices for selecting and applying a food grade stain for wooden surfaces?

When selecting a food grade stain for wooden surfaces, it is important to choose a product that is specifically labeled as safe for use on surfaces that come into contact with food. Look for stains that are non-toxic and free of harmful chemicals. Before applying the stain, make sure the wooden surface is clean and dry. Apply the stain evenly with a brush or cloth, following the manufacturer's instructions. Allow the stain to dry completely before using the surface for food preparation.
