But before you do this, try leaving the swazzle to totally dry out. Leave it a couple of days. Then soak it again and try all over again - you may find it now works perfectly. Don't ask me why, I don't know. Also swazzles can go "out of tune", and yet recover simply by being ignored for a few days. For this reason it is a good idea to make several swazzles and use them in rotation.
