I rinse them with the hose inside and out then when I get a bunch of them I wash them in the washing machine with bleach, then air dry. Then I soak them in a bucket of rodi water and prime then air dry again.
People have differing ways of doing this. I was mine in the clothes washer with bleach. I then put them out for the day to dry. In the sun is better I think.
Rinse with a hose inside out, then straight to a bucket to soak in oxiclean, end of the week I throw in the wash with extra rinsex2, then dryer on medium heat. Come out looking brand new .
I would put them in the washing machine with bleach. When they were done I built a pvc hanger and would hang them for a few days to make sure any bleach that's as left dissipated.
I place mine in the washing machine on the sanitize cycle (1 hour and 45 min in 175F water) with soap and a second rinse. Then I wash them again on the quick cycle just to be ertain all of the soap is out.
I rinse mine out, then keep them in a bucket with vinegar until I have a bunch then wash in hot water with 3 cups of vinegar with an extra rinse. They come out perfectly white no odor.
I don't have to worry about soap or leach contamination.
I am assuming all of you that machine wash your filter socks you are using felt socks? I use mesh socks and a simple rinse in the sink and they are clean.
I wait till I have at least 4 and put them in a bucket with bleach and water overnight. Then rinse well with the hose and let air dry. No problems here.
I rinse them out in a small 1/2 gal bucket in the sink then soak in bleach for a days followed by a good rinse then a soak for a couple of days in fresh water. I let them dry until they are needed again. Sometimes they are dry, other times they are not.
I used bleach for years and never noticed any bad in the tank. The process took a lot longer before I could use them because I wanted to make sure the bleach evaporated fully. I never got over the bleach smell in the sock though, always made me nervous and even using prime didn't help the smell. After using oxiclean I'm never going back. The socks are really clean, no odor and after 30 minutes in the dryer they can go right in the tank.
I put mine is the washer with a splash of bleach and some vinegar. Hot water with extra rinse and then put out side to dry. I like the oxiclean idea.
The dryer makes me nervous. I worry about fabric softener residue.
I soak mine in a bucket with bleach. Then I rinse it out with tap water, then I soak it in tap water for 2-3 days. Then I rinse it with RODI water before letting it dry.
