I've been using Bentonite Clay for a binder and tooth brushing. Have used a certain brand powder and been fine with it but noticed that the last two bags I have bought have a smell, like a perfume smell. I've read that that kind of smell can mean it has gone bad. Was refunded for first bag - smell was very strong. This second bag, smell is not as bad but there is a little. Not sure whether I should use it? Anyone else have this issue? Thanks.

Thanks. Been buying this on ebay. Will probably try another brand next time.
