Musical gear maintenance and value preservation guide
How to maintain, clean, store and document musical instruments and audio gear to reduce deterioration, avoidable failures and loss of value.
Faders, potentiometers, switches, keyboards, grilles, jacks and gaps can allow liquid to reach hidden areas.
When external cleaning requires a product, apply a minimal amount to the cloth rather than directly to the equipment unless the manufacturer instructs otherwise. Prevent liquid from running toward openings and connectors.
Electrical contact products are not general-purpose cleaners; use them only when appropriate for the component and with the correct procedure.
Dust and residues are not only cosmetic. They can accumulate in gaps, fans, potentiometers, faders, mechanisms and connectors.
Smoke, aerosols and marine environments can leave harder-to-remove deposits and encourage corrosion or sticky surfaces. After use in demanding environments, careful external cleaning and inspection of exposed points is more useful than waiting for an annual service.
Do not blow contamination deeper into equipment or spray products into controls without a procedure suitable for that component.
A vibration or rattle does not necessarily come from the speaker itself.
From the outside, inspect handles, casters, panels, grilles, screws and objects resting on the cabinet. Inspect the cone when visible without unnecessary touching, and make sure external cables and connectors are suitable for the connection.
If a speaker or internal wiring fault is suspected, avoid tests that could overload the amplifier and verify that impedance and connection follow the system specifications.
Light surface oxidation is different from active corrosion, pitting or material that is flaking away.
Periodically inspect metal parts, screws, bridges, tuners, chassis and connectors. If deterioration is progressing, identify the cause first: humidity, perspiration, contaminants, leaks or unsuitable storage.
On vintage gear or original finishes, aggressive cleaning can remove plating, markings or historical patina. When uncertain, document the condition and consider specialist work.
On acoustic and semi-hollow instruments, unusual changes in action or intonation may accompany structural movement.
Inspect the bridge, top, joints, binding, neck and any new cracks or openings. Do not automatically treat every seasonal movement as a defect, but document changes that continue to progress.
If cracks, separation or obvious deformation appear, avoid aggressive setup changes that may mask the issue and have the structure assessed.
