You can use things to separate the reeds. Some use tooth picks or break off pieces of a plastic fork. I don’t use them,I prefer to pat them dry with a paper towel and let them air dry on the counter. Then put them in a snuff can with holes drilled in it. Store in the frig every day.
They will will be slightly stuck together when dry, reverse the call and blow into the cut reeds and try to push saliva into them, keep running the call in the car on your way to hunt, they will separate.

Some mouth wash can be hard on the tape adhesive, if you choose to use mouth wash use alcohol free.
