Don't go too crazy, though, there are ball bearings in many linear grippers that might not roll so well with cleaner residue on them.
I agree with DD, the ball bearings should not be cleaned, as they may rust if using a a water based product or alcohol. If that does occur, lubricate with oil or even better grease. WD-40 is good for a short time, as it dries out quickly. A PTFE grease, like Grease Lightening or CLP Break Free is what I use.
As for RPM Blast, it has a PTFE (Teflon) coating which transfers to the gripping surface of the tensioner.
