WD40 now do a proper 'fast drying contact cleaner' that works well (not the basic WD40), but it's not lubricated, so more like the straight Caig's DeoxIT. Though Caig also do a separate lube-only spray, CAIG DeoxIT Faderlube F5. It probably makes more sense to first clean out and then lube, rather than do both at the same time (although it is more convenient).
