i boil up some calandula flower tea and some chamomile tea (antiseptic and soothing combination) and add that to the water.
As wipes i just buy a metre of fleece from spotlight (about $9) and cut it up. they wash really well - i actually bought 2 metre, in 2 diff colours, one for liners and one for wipes.
Fantastic buy,, so cheap and never had a problem
