Depending on the type of musical instrument, there are certain things that should be done in order to prepare it for the time in storage. For example, string instruments should have the strings loosened to relieve the tension and drumheads should also be relieved of their tension. Of course, like everything else that goes into a storage unit, the musical instruments should be properly cleaned and dried. This is especially important for the reed and mouthpiece of a wind instrument so that mold or mildew does not develop from residual moisture. As an added measure against damage due to dampness, small desiccant packets can be placed with the musical instrument.

Another part of storing them that depends on the type of musical instrument is how it is packed for storage. Many instruments have specially made carrying cases with separate compartments for the various parts. Obviously, this is the best choice because the separate compartments are form fitted to the pieces and give them the maximum protection from damage due to impact. If there is no case for the musical instrument that is being put in storage it is advisable to contact a store that sells musical instruments and ask them for the best way to protect it during the move and the time that it is in the self storage unit.
