I might have put my Orvis breathable waders away before they were completely dry, only to discover after more than a week they smelled strongly of something (probably mildew). I washed them in the washing machine and hung them up to dry inside and out. It seems the smell went away from the breathable material, but remains strong in the neoprene feet. Is this condition correctable? Although I know that Tilex is a mildew killer, but should I risk what it might do to the material? If so, what should I do?
