I carry them in the field in one of those rubber football shaped change holders and when I'm done for the morning I will wash them good under the kitchen faucet and then lay them out on a paper towel to dry. Toothpicks work to keep the reeds separate but I usually don't bother. I can break them loose again in no time enroute to my next hunt by doing a little warm up. Occasionally I will soak them in 'Scope but even then I rinse them under the faucet and dry em out on a paper towel. Germs/bacteria just don't do well in a dry environment.
