How do you bath a guinea-pig?

your not suposed to really give them a bath u get dust form a pet store for them to roll in that is made just for them and they roll in it and get cleaned. give it a box of sand then it will roll in it when it feel dirty, too much water on a chinchilla could kill it cause the fur might keep it from drying and it could get to cold and die cause of water, a chinchilla need to be look after real carefully, they take sand bath by themself
