Thank you for the info about the filer socks, I will need to know that soon5 gallon jugs I bought online that are only used for water storage.
I second the bleach it out, with the caveat that I would rinse them really well and let them sit with water and prime for a couple days to neutralize the bleach.
I clean my filter socks in the same manner. Let them soak in bleach overnight, then in RO/DI and prime overnight.
