Noalox has no place at all on any of my vape gear. DeooxIT D100L and G100L is all I have used on my Reos. Medical cloth bandage tape folded over on itself (sticky to sticky) then cut into strips with a little alky or D100L is what I clean any carbon off my contacts with (followed by a little G100L). Abrasive enough to get it off easily, not abrasive enough to damage the contacts.
