Dust the wood surface with a feather duster or a soft cleaning rag.
Place a small amount of white -- not gel -- toothpaste onto a soft, lint-free cleaning cloth.
Rub the toothpaste into the wood surface. Use movements that go with the grain of wood. Continue rubbing until the spot disappears.
Wipe off any remaining residue with a clean section of the cloth.
Wax the surface of the wood. Another idea is to mix 2 parts sweet oil with 1 part apple cider vinegar in a clean, plastic spray bottle. Shake well and spray it onto the surface of the wood. Polish as usual with a soft, lint-free cloth.
Dip some steel wool or a paintbrush into paint thinner or turpentine. Spread it over the wood finish. Work quickly before the solvent evaporates.
Rub or brush the solvent onto all the wood surfaces to dissolve the finish. Make sure all defects are gone.
Smooth the surface of the wood by using long, light strokes. Rub or brush with the grain of the wood.
Buff the surface with 0000 steel wool once it is dry. Do this over the entire surface. This smooths out any rough spots or edges on the wood.
Use a paste wax on your wood furniture, following the directions on the package. The wood finish will shine like new.
