Naturally repair wood w/vinegar and canola oil
Naturally Repair Wood With Vinegar and Canola Oil ... Super cheap, use 3/4 cup of canola oil, add 1/4 cup vinegar. white or apple cider vinegar, mix it in a jar, then rub it into the wood. You don’t need to wipe it off; the wood just soaks it in.
P.S My own thought on this, I'd have to see it done it real time to decide if I'd try to wipe off the excess (if any) or not.
