i use crayon that matches the wood or as close as you can get. I allow it to sit while I do something else. When I go back I use my pledge furniture polish apply a spray and use an old rag and buff the crayon lightly!! It will usually last for a long while. Or try shoe polish dye which is hard to find and apply it allow to set and then buff it with furniture polish. Best of luck!!
Not really that good for wood, use Old English dark tone polish and scratch cover-up. Works great.

Cooking oils go rancid. I use Old English polish (dark for dark wood, light for light wood).
There are also furniture repair pens.
