Soften the adhesive residue with a hairdryer. Set the hairdryer to the "Low" or "Medium" heat setting. Hold the hairdryer a foot above the wood surface and direct the heat toward the adhesive for one to three minutes.
Moisten a clean cloth with warm water. Wring out the excess liquid.
Add two drops of liquid dish-washing detergent to the damp cloth. Gently scrub the softened adhesive to loosen it. Rub back and forth to cause the adhesive glue to ball up and pull away from the wood.
Wipe the wood surface with another damp cloth to rinse off the dish-washing detergent.
Treat any remaining adhesive residue on the wood surface by scrubbing it off with a cloth dampened with warmed, full-strength vinegar. Use the vinegar to remove the last traces of adhesive.
Rinse the wood surface with a damp cloth. Dry it with another cloth.
