This one is super easy. It has only two ingredients, is easy to mix up, and works really well, especially on leather gloves after they get all crusty and dried when it rains.
In an old olive oil bottle, mix ½ cup extra virgin olive oil and ¼ cup lemon juice. Shake well and tip onto a rag to polish surfaces. Make sure not to use too much, or it will leave smudges and residue on wood.
The only thing I don’t like about this recipe is that it might go bad before you get a chance to use it all up. You’ll know simply by looking at it when it’s turned bad: it thickens and starts to turn brown. It will keep for quite a while though, so maybe making half a batch will work a little better. I think I’ll try this the next time I need to make it.
