Dusting or vacuuming with a soft brush attachment is all that’s usually necessary. When heavier cleaning is in order, wipe with a cotton cloth lightly dampened with a solution of one teaspoon of mild dishwashing liquid (one without hand moisturizers) mixed with one gallon of water. Applying a clear paste wax no more than once a year will slow dust and dirt buildup, protect the wood from water damage, and make the color more vibrant (if the paint is chipped, don’t wax the wood).

Dish Soap

A gentle formula like Ivory ($3 at grocery stores) is simplest and best for cleaning painted wood.

Paste Wax

Clear MinWax Paste Finishing Wax ($7.50 at hardware stores) provides a protective layer.
