Keeping your arcade machines in pristine condition is crucial for both their longevity and gameplay experience. Proper maintenance prevents common issues like sticky buttons, dim monitors, and internal dust buildup. Here are the best practices to follow.

First, always prioritize safety. Before any cleaning, unplug the machine from the wall outlet. This protects you from electric shock and prevents damage to the sensitive internal components. Allow any powered components, like the CRT monitor, to fully discharge before proceeding.

For general exterior cleaning, use a soft, lint-free microfiber cloth slightly dampened with distilled water. Avoid harsh chemicals, ammonia-based cleaners, or excessive moisture, especially on wooden cabinets, as they can damage artwork and finishes. For tougher grime, a mild soap solution can be used, but ensure it is applied to the cloth first, not directly on the cabinet.

The control panel requires careful attention. For buttons and joysticks, use isopropyl alcohol (70% or higher) on a cotton swab. This effectively dissolves grease and grime without leaving residue. Gently clean around the base of the joystick and the surface of each button.

Cleaning the CRT monitor screen is delicate. Never use glass cleaner! Instead, use a screen cleaner designed specifically for monitors or a dry microfiber cloth. Gently wipe the screen in a circular motion to avoid scratching the anti-glare coating.

Internal cleaning is essential for preventing overheating. Use compressed air to carefully blow dust off of printed circuit boards (PCBs), wiring, and fans. Hold the can upright to avoid spraying moisture and keep the nozzle a few inches away from components.

Finally, establish a routine. A quick external wipe-down should be done weekly. A more thorough cleaning, including the control panel, should be performed monthly. Internal dusting can be done every 6 to 12 months, depending on the environment. By following these best practices, you will preserve the value and functionality of your arcade machine for years to come.
