Maybe this article will answer your question:
Is this what you're looking for? It looks like this is more for repairing wood than cleaning.
Hi Susan. I've heard of salt and oil to clean and remove water marks from wood. The salt draws out the moisture and the oil conditions the wood. I use Murphy's Oil Soap on my kitchen cupboards and been happy with results. Good luck Susan and Happy Holidays.
Mix a quarter cup of olive oil to a quarter cup of white vinegar. Use a soft cloth, apply a small amount of the mixture to the wood and buff the wood to a shine. The oil should replenish moisture to the wood. Again, you should test a small area first. From my reading it seems using canola oil is to repair scratches, not just to clean.
