Wow, lesson learnt.

I run my washer through once empty to rinse any soap residue, then stick the filter socks in by themselves with a 1/4 cup of bleach through a heavy wash cycle and an extra rinse cycle. Let air dry for a day after that.
Probably over kill, but works for me.

"not thinking anything of it', will get ya nearly every time. Anyway...
I turn inside out and wash by hand, then soak in water till I have a few piled up. Extra cycle , bit of bleach, NO soap, air dry as long as possible.

Do all the same here except I do not do the pre-rinse of the washing machine.

I power wash mine , built a round wire mesh slip them over and power wash away then hang to air dry

First I turn mine inside out and wash them by hand under warm water then soak them in Hydrogen Peroxide for a day. Then they go in the washing machine on high temperature, no soap. I also run a quick rinse cycle on the empty washing machine before putting the filter socks in.

I read somewhere that Hydrogen Peroxide is a more safe method than bleach. Not sure if it's true or not but it seams to get the job done.
