My fave were from Bits for Bots - bamboo terry/bamboo velour. LOVED them. But Donna doesn't make them anymore [lucky my last is out of naps lol I wore the ones I had out!]
But I had a nice mix. I wasn't fussed on the ones that used flannelette.

Water straight out of the tap [warm], or soaked in tea tree or lavender.
Nappy rashes I soaked them in a cammomile/tea tree mix.
