My regiment is to wash my clothing when I take it out of storage. I store over the winter and summer in plastic lawn and leaf bags and then inside a rubbermaid tote large enough for it all.
I run my washer once on as hot a setting as I can whle its empty, also pouring boiling water inside the bleach holder, faberic softener dispenser, etc the clean them out.
I then wash in cold/cold with everything inside out and then again in cold/cold with no sopa for a good rinsing.
I line dry them outside for about 2 or 3 weeks. Still inside out to protect the color from the sun.
I like to have my stuff rained on at least once then air dried again.
Then back into lawn and leaf bags tied shut if its rainy out siode during the hunting season.
I try to keep my clothing outside being air dried as much as possible even after daily use.
I do not use nor believe scent lok stuff works.
This has work very well for me over the past 17 years.
