This is why I've been using food-grade orange oil, nothing but the oils from orange peels obtained by cold-pressing them after extraction of the orange juice. You can add a little of the very same stuff to your lemon merengue pie or lemon cookies for a tastier treat.
I do however wash and dry the components after degreasing them as I don't really think this stuff is good around chain lubricant or grease.
The stuff I use comes from this website: http://www.greenterpene.com/
