I change ds using flannels wetted under warm water ... DH uses cotton wool. There are disposable wipes in the change bag and a dry flannel or 2 - I can use water as normal, or a wipe and dry ds so he doesn't get sore.
Cheeky wipes we got very cheaply before Ewan was born and a few random bv / fleece etc that we've picked up along the way. Mostly I used them with plain water.
We use washable wipes, mostly home made in bamboo terry with either minkee or bv the other side. I do have a few Looby Lu's & Green Panda one's for best
