To protect reeds, store them in a reed guard of some kind that will keep them flat. Wet reeds kept in the paper cases or boxes wherein they were sold will not stay in good gambling shape, as they aren't capable of dry in a flat place. A good reed case could be made from a hard material plastic or with a pitcher plate, will offer protection to the top of the reed and will keep the reed held securely on a dry, flat surface. The clarinet can be kept free of dirt and dirt by dusting under the keys with a soft brush on a standard basis. To keep keys moving efficiently and noiselessly, apply a small drop of mainly formulated key oil where the key rods meet the posts. Do this on a month-to-month basis, and be certain all dirt is removed before applying the oil. Use a needle oiler, and take care that no oil comes into contact with the plastic body of a scholar instrument. Check to see that the screws are in place and have not twisted themselves out of the post. Lost screws will mean lost keys. If the screw is too far out, tighten it with a small screwdriver until it is level with the post, but do not overwind the screw, as the important thing may bind. If unsure, hunt down a professional repair person to fix, hold and adjust screw tensions.
