I just chuck DDs doll in the washing machine. She used to be a talking doll, but that drove me mad anyway, so I ripped out the battery and wires, and off she went in the washing machine

. I told DD and we watched her tumble around for a while. DD doesn't mind at all. I wash her in the morning, and it doesn't really take that long to dry.
(I do have a front loader. Not sure if the thing inside a toploader would damage a doll)
