Those do it yourself car washes are good for wader cleaning, get your wife or a close friend(someone who will not laugh their head off at you) to go with you, put your waders on and have your accomplice use the power spray wand with detergent on you while you spin around. Be careful how long you allow the high pressure spray to linger on you crotch area though, unless you don't embarass easily. Then go for the brush w/soap and finally the rinse. THAT SHOULD DO IT! then take your waders and ski mask off( what!, you want people to recognize you?) and your waders will be squeeky clean!
To patch a hole in those same waders use Aquaseal, it's the only product that will do the job right.
