I just use old tshirts or those makeup applying/removing cotton pads like these. Put some on, rub in a circle, slowly let up on the pressure until you feel done. Keep continuing until you don't want to add anymore wax; I don't see any improvement in adding more than 2 coats of Renaissance Wax.

Why? As in to use with waxing or instead of waxing just print with more black? I'm assuming the latter, but most people aren't looking for "more black", but a deeper black (higher dmax). Waxing will help the tiniest bit here, but if someone wants a deeper black then they need to look at their printing workflow. The worst offender I've seen in many alt labs is the low humidity during exposure from a variety of reasons causing anemic blacks in prints.
