Lemon Oil

So called “Lemon Oil” is just a lemon scented consumer grade product. It doesn’t contain much of anything except solvents.

Use a real wood finishing oil, such as linseed oil or tung oil.

I prefer Boiled Linseed Oil for the purpose you are describing. However, it will likely change the color (darken) of your wood. If the wood isn’t too far gone, it will do a nice job of bringing it back to life.

I try to discourage my customers from using these type of products (Old English, Liquid Gold, etc) because of the buildup that occurs from repeated use. I once tried to “spruce up” some kitchen cabs that had been regularly “cleaned” with Liquid Gold, and had to give up when I found that the “gunk” buildup was going to require a total strip and refinish to look right.

I would experiment with BLO or Tung oil and use that if it doesn’t change the color of the wood too much.
