Stuffed animals.
Kids often keep their stuffed toys close, so you’ll want to be very careful when purchasing them used.
According to Six Dollar Family, kids’ teddy bears can carry germs, odors, bedbugs, mold, and allergens, among other things.
Though you can clean a stuffed toy by washing it in hot water and using heat to dry it, this could wind up disfiguring it. This method isn’t foolproof, either, and germs could still linger after sanitation.
