Stain the Wood
Use a rag, a soft sponge or a brush to apply the stain. Move with the grain, not against it. The longer you leave the stain on, the darker the finish.
Note: Stain is either oil- or water-based, although some hybrid products are available. Water-based stains are nontoxic and clean up easily with water but have a tendency to cause streaking. Oil-based stains, available in liquid or gel form, are more user-friendly; however, they produce stronger fumes and are harder to clean up.
