I use cloth wipes - just cheapo thin face washers from Big W/Coles that come in a 12 pack. I have 24 and wash every 2nd day, but don't come anywhere close to running out of wipes. If it's a big poo, then I'll probably use 3 wipes (but these face washers aren't huge). I don't use a foaming cleanser with them. I have a spray bottle that is mostly water with a squirt of babywash and 2 spurts of sorbelene cream - cheap and easy! I then spray onto the cloth wipe, and wipe away. DS hasn't had any nappy rash at all with this regime.

HTH!
