Cleaning Filter Sock

[Lampshade]

I used to hand wash. I suck at it, if I was in the 1800's and unmarried I'd be screwed. I've started using the washing machine and they come out white, better than I could do. Only issue is that they get pretty beaten up, i ordered some cheap ones that lasted maybe 5-6 washes. I've started using the gentle wash on the machine and seems to be better and still cleans them. No detergent or bleach. I even do a quick wash with just water to make sure the soaps gone... good for washing the dog blankets in :P.
