Hey Steve,
I think there was a thread on this either on this site or BCFR about it sometime back; I seem to washing in a mild detergent of some kind.
I have always washed my Helly "offshore" pants (not the rubber Helly pants...they are more similar to Mustang) in the washing machine (cold water) with "Zero" (I think that was the brand) and then just hung them to dry; they are still 100% waterproof after about a dozen washes.
Whether your just gave them a wash in a big sink....or in the machine I think they should be okay. Is there a "washing instrucitons" tag in them?
Here is some info from Mustang's site....I guess I should maybe use warm water.
