So, I took some dirty filter socks out of storage and decided to use them again. These are the nylon, non felt, type. I set them next to the sink in the wash room until I could rinse them out. Next thing I know, they have been through the washer and dryer. They certainly look clean but what about the detergent and dryer softener? Do you think they are good to use or should I run them through the washer again with no soap and no dryer sheets? Just curious as to what the masses think. thanks
