Editing Atari 800 General Maintenance (section)

== Regular Cleaning ==

=== External Case and Keyboard ===
* Wipe the ABS plastic case with a '''damp microfibre cloth''' and mild dish soap. Avoid harsh chemicals.
* For yellowed plastics, '''retrobrite''' is possible, but monitor temperature and exposure to prevent warping.
* Remove keycaps vertically for deep cleaning. Clean key plungers and contacts with 99% isopropyl alcohol (IPA).
* Lubricate stabiliser wires with plastic-safe grease if keys feel stiff.

=== Internal Cleaning ===
* Unplug the Atari 800 and allow a few minutes for capacitors to discharge.
* Remove the top cover and metal RF shield to access the mainboard.
* Use compressed air or an anti-static brush to remove dust from the PCB, cartridge slots, and module bays.
* For stubborn grime, use IPA and a soft ESD-safe brush. Ensure all parts are dry before reassembly.
* Re-seat all socketed modules (CPU, RAM, ROM) to wipe oxidised contacts.
