I don't know how nobody can get their socks clean. Firstly, I started off buying 25 custom made, 50 micron (7x16) socks from filterbag.com. They cost me about $3 per sock with shipping. So there's plenty of extras and you can get any material and with/without plastic ring.
Secondly, after I take out a dirty sock I place it in a home depot bucket and pinch the top of the bag between the folding handle and the bucket, so the bag is suspended and air-dries the bag out back.
Third, I flip the sock inside out, when dry, and stick it in a 2 gallon bucket with screw-on lid (found as a set on Amazon), filled with peroxide to soak them. (I found a place to buy a case of four 1-gallon jugs cheap if anyone is interested). They soak until I have about 6-7 stuffed in there. They I take those and they hit the washing machine for a few rinses.
I never use a hose or sink to rinse them. The peroxide breaks down all the funk. They must also be completely dry when you put them in the peroxide and turned inside out.
If you use socks, you have to have plenty of extras on hand and not be paying $7-$10 a piece for them. I still have half of the socks I haven't even opened yet of the 25. It's effortless.
There was a person that did a microscopic study on cleaning socks and found that bleach just whitens bits of algae in the sock, but peroxide actually removes it.
I really like the DIY idea, but I have to use flexible filter socks. My sump is so cramped I have to bend them a lot to maneuver them into the holder.
Forsaken77 - What concentration of hydrogen peroxide do you use in the bucket? Or do you use is straight, using the four 1-gallon jugs you mentioned? Thanks!
