Remove glue from wood by using WD-40, vegetable oil, acetone or fine grain sandpaper. Try the cleaning agent on a small unnoticeable part of the wood first to make sure that it doesn't damage the wood before using the product to remove the glue.Continue Reading
Use a cloth moistened with WD-40 or vegetable oil to loosen glue from wood. Gently buff the glue in order to loosen it from the wood. Don't apply the oil directly to the wood around the glue unless the wood is varnished.
Acetone is also very effective at removing dried glue from wood. Apply the acetone to the glue using a small paint brush, and gently pry the softened glue away from the wood using a cotton swab. Work from the outside edges of the glue toward the center in order to avoid damaging the wood.
A more drastic approach to removing dried glue from wood is to sand the glue away using sandpaper. Frame the glue with masking tape in order to protect the surrounding wood. Sand down the glue using 600-grit sandpaper until the glue is almost flush with the wood. Finally, use 1,200-grit sandpaper to remove any remaining glue residue, and wipe the area with a damp towel.Learn more about Carpentry
