How to wash non washable toys?

Help!!! How do I wash toys that have battery packs in them? My LO have lots of toys that are soft but have battery packs in them so they can go in the washer. I used to just use wipes but now they’re getting older their toys just don’t stay clean and keep getting stained. I really don’t want to throw them away because my girls love them. My girl has a dancing Bluey that she loves but it’s filthy and I have no idea how to get it clean 😫 Any tips on how to get them clean?? I’m anxious about washing them and getting them to wet with them being battery powered.
