Editing Apple Hard Disk 20 Maintenance (section)

== Cleaning and Preservation ==
Proper cleaning ensures longevity and functionality.

=== External Cleaning ===
Clean the enclosure with mild detergent or isopropyl alcohol. Avoid harsh solvents. Consider retrobrite treatment carefully if yellowed.

=== Internal Electronics Cleaning ===
Use compressed air and brushes to remove dust from electronics. Clean corrosion or sticky residue gently with isopropyl alcohol and cotton swabs.

=== Rodime Drive Cleaning ===
Avoid opening the drive unless necessary. Clean external contacts gently. Internal cleaning should only be performed in dust-free conditions if head stiction occurs, using 99% isopropyl alcohol and lint-free swabs.

=== Preventative Preservation ===
Consider replacing electrolytic capacitors in both the power supply and Rodime logic board. Replace degraded rubber components. Store in a low-humidity, stable environment.
