I didn't have the washer option. I used to throw them on the cement floor, get the hardest flow I could get going with the garden hose nozzle, and beat the heck out of them that way. After it I would soak in a bucket with a bit of bleach, then soak in a bucket/rinse with some water and dechlorinator and done. Always have at least one back up filter sock so that you have time to do all this, otherwise you have a tendancy to avoid changing the sock -->nitrate problem.
The hose and washer method should be fine, though residue from the detergent would scare me...but then I am easily scared. Not by bleach, but by other stuff
