When I do wash my gear I actually do use a washing machine, the horizontal drum type, with cold water on a gentle cycle and always extra rinse. A few pieces of gear at a time, either no zippers or with zippers fully zipped, will go into a mesh bag for delicates. For detergent, I use a small amount of Tide "Free and Gentle" liquid. After the cycle, the gear then goes onto a drying rack where I do my best not to let too much of it hang under its own wet-weight. It dries indoors, out of the sunlight, usually with a fan gently blowing on it.
