Use real wood turpentine for best results, not turpentine substitute. Shred 2 oz. of beeswax into ½ pt. of turpentine. The mixture needs to be warmed gently to mix it; a dish over a pot of hot water is ideal. Do not cover. Add a little essential fragrance oil to the mix once it starts to cool, if you wish. Apply the polish with a soft cloth.
Beeswax conditioner protects wood and brings out the grain. Moreover, beeswax is a natural waterproofing agent, and so resists rings from wet glasses. A benefit of making your own conditioner is that you know exactly what it contains; you can avoid ingredients to which you are allergic or simply don't like.
Apply this conditioner when it is slightly warm, to ensure the greatest penetration into the wood. Do not let a home mixture simmer or boil, and do not use a microwave, as turpentine is highly flammable.
