Hey Ladies, the family we are staying with has a washer that is hooked up to a water ionizer. Because the water is ionized, they don't use detergent. But when I smell the sheets and towels they gave us, they have a scent to them, even though they don't use detergent or dryer sheets or anything.  Does anyone have any info on how these ionizers work or if they have a chemical in them that would cause a scent?  I'm really nervous to wash my clothes in this washer.  Thanks.
