sounds like you need to do atrip wash, sophies smelt especially the hemp but where fine after, i used a little washing detergant at 60 degrees, i occasionally use the dettol rinse as well if there smelly
i dont store them seperatly but yes the smell burns my nasal hairs!! ive started ot put power in the bottom of the bucket in hope it will absorb some of the smell

do you dry them outside??? mine smell if they dont see the sun
