Nearly all my PP collection has been through a pillow case wash cycle, but eye paint can come off, so to be extra careful I'd make sure there is a double layer of fabric around the face or a flannel inside or something, and you wash it amongst towels or bedding or something to pad the washer out. I have Oxy bathed a couple of pups but I don't like squeezing the poor things dry as the stitching can pop on the 80s pups! On several of my pups the washing labels faded after a wash cycle too, so if it's a particularly good condition vintage pup, I now put them in a bag in the freezer for a while to kill any dust mites or whatever, then Febreez them.
