Long ago we used cigarette paper. The same paper is now accessible as pad drying paper in order that young scholars may get it easily from music stores. Drying the clarinet successfully will keep it clean and also help prevent cracks from coming up in a wood bodied tool. Teaching this to scholars who have plastic clarinets can assist ensure that they continue to dry their devices completely when they eventually step up to wood. Make sure that your youngest students know the way to place the parts of the tool back into its case appropriately. The upper and lower joints must fit into the case in the accurate path to ensure that it to close properly, and the case shouldn't ever be forced shut like an overstuffed suitcase. If the pieces are of their proper positions, the case should close securely but easily. The mouthpiece might be placed in the case with the ligature on it, and then the mouthpiece cap could be placed over both, with care being taken not to nick or crack the facing of the mouthpiece by hitting it with the cap. I prefer plastic caps because of this. It is better to take the reed off the mouthpiece before storing it. Reeds left to dry on the mouthpiece can warp, with a view to lead them to play badly in very little time.
