Basic Wood Cleaning Formula
This formula is for well-used furniture. The vinegar works to pull dirt out of the wood. It doesn't leave an oily residue because the little bit of oil keeps the wood from drying out. It will store almost indefinately in a lidded jar.
1/4 cup white distilled vinegar
1/4 cup water
1/2 teaspoon liquid castile soap
5 drops jojoba or olive oil
Combine the ingredients in a bowl. Saturate a sponge and squeeze out the excess. Wash surfaces of tired and dirty wood. The vinegar smell will disipate soon. Dry with a soft cloth.
