Keeping arcade machines operational for years requires consistent maintenance routines that preserve both their electronic components and physical structure. Begin with regular external cleaning using appropriate solutions for different surfaces - mild soap and water for cabinets, glass cleaner for monitors (when powered off), and isopropyl alcohol for control panels. Internal maintenance should include monthly dust removal using compressed air to prevent overheating, particularly around power supplies and PCBs.

Electronic components demand specific attention: monitor calibration for optimal picture quality, power supply voltage checks, and thorough inspection of wiring harnesses for fraying or loose connections. For the mechanical aspects, button and joystick mechanisms require periodic disassembly, cleaning, and replacement of worn microswitches. Coin mechanisms and doors need lubrication with appropriate products to ensure smooth operation.

Establish a preventive maintenance schedule that includes daily visual inspections, weekly cleaning routines, and quarterly comprehensive internal checks. Keep detailed maintenance logs documenting all service activities, replacements, and emerging issues. Proper environmental control is crucial - maintain stable temperature and humidity levels to prevent component degradation. Always use authentic replacement parts when repairs are necessary, as compatible components may not meet original specifications. Following these structured maintenance practices will significantly extend your arcade machine's operational life while preserving its play quality and value.
