I wouldn’t put them in the washing machine. Lather then up with a bit of dish soap and rinse clean
I wouldn't put in washing machine, sponge them down with fairly liquid let it dry then use wipes to make sure germs are all gone
I put rattly/crinkly toys in the washing machine on hand wash/delicates setting and then try on the radiator do they don't stay damp/mildewy and dry as fast as possible
I’d probably do boiling water, Milton tablet and give them a good scrub x
