I use the Washy Wonder in my dishwasher to wash plastic sandwich bags like this one from my kids’ lunch box. I don’t use the dry cycle on my dishwasher so the plastic bags that are washed tend to be a little wet – kind of like wet plastic Tupperware. I take the bags and use a plastic chip clip (don’t use metal because it will leave a rust streak on the bag) and then stick them on my refrigerator. They dry during the day and the next morning I reuse the plastic bags in the lunch box again. You can also use a wooden bag dryer to dry the plastic sandwich or other sized bags.
