My concern would be residues left behind by these shticky rollers. Even a microscopic film can build up over time and transfer to you stylus.
As far as cleaning the gooves (or getting in there), if wood glue works, maybe these will as well. But pulling particles out does not mean they won't leave their own crap behind.
