Thanks for the info. I will wash them, treat with armorall, and hang them up. I live in Texas and hang my waders in the garage where it will get hot in summer. I would prefer to hang them in my closet in the cooler air, but my wife is against that. I guess I'll just be comforted by the thought that I have done what is in my power to care for and extend the life of these waders and just buy a new pair when needed, even if their life is somewhat shortened by the exposure to summer heat. In any case they are not immortal, and I will ultimately need to replace them.
