Repair of Machines d(‾o‾)b

Update:

I bought a second-hand PSP. Its work made a noise. I used a chain lube, it’s semi-dry type and not contained abrasive.

To a gear of the optical drive. When I sprayed the chain lubricant, I covered PSP’s optical lens with a lens cleaning cloth for camera. I sprayed very small amount, and waited the permeation to deep placed parts for 10 times reboots.
The PSP is working quietly now.

All above is self-help with my own responsibility.
