That looks like a good way to clean them. Just curious...have you ever tried an ultrasonic cleaner?
Nice!Would you be able to substitute malt vinegar if you don't have citric acid, do you think? Maybe it would be too strong....
Not Malt! that stinks. Vinegar is also quite a bit stronger and starts bleaching any colour out of the nylon. A handfull of times its ok, but after that they start fading badly. It’s good for cleaning showers though
I've found that simple soap and water wash and air dry has worked out the best for me.
