A Great Wood Conditioner
Here is a product I used to great effect. Unnecessary backstory: I tried an experiment of keeping my loud new cat in the basement during the night and my new cat experimented with clawing the wood basement door, trying to get out. Mineral Bee Wood Conditioner, a food grade mineral oil made with beeswax, covered up the scratches beautifully. I’m looking for other uses too. The cat, by the way, won. No more basement. Ear plugs are doing the trick.
