If peanut butter works, then peanut oil would presumably work better, without the extra peanut bulk (or sugar). My guess is that ground peanuts are not a useful abrasive, but who knows?
If peanut oil works, then any other vegetable oil seems like an easy-to-try and more readily available option. We have canola and olive oils in the cupboard, and if going for oil I would try those.
