Editing Osborne 1 General Maintenance (section)

== Regular Cleaning ==

Dust, grime, and oxidation are common threats to the Osborne 1’s longevity, especially given its compact, luggable design.

=== External Case and Keyboard ===
* Wipe the ABS plastic case with a '''damp microfibre cloth''' and a drop of mild dish soap.
* Avoid harsh solvents or abrasive cleaners, which can damage the textured finish.
* The detachable keyboard can be cleaned with isopropyl alcohol (>90%) and a soft brush.
* Keycaps may be carefully pried off for deep cleaning; clean plungers and stabilisers with IPA and re-lubricate with plastic-safe grease if sticky.

=== Internal Cleaning ===
* Unplug the Osborne 1 and allow a few minutes for capacitors to discharge.
* Remove the top cover to access the motherboard, CRT, and floppy drives.
* Use compressed air or an anti-static brush to remove dust from the PCB, CRT neck, and PSU area.
* For stubborn grime, gently wipe with isopropyl alcohol and a lint-free cloth.
* Ensure all components are '''completely dry''' before reassembly.

=== Floppy Drives ===
* Clean drive bezels and eject levers with a damp cloth.
* Use a '''floppy drive cleaning disk''' to clean the read/write heads periodically.
* Remove dust from the drive mechanism using compressed air; avoid direct contact with the heads.
