My mechanic dude suggested the the cause of the engine's periodic but
brief loss of power during grade climbs last week might be a dirty spot
on the AFM track and suggested gently cleaning it with a pencil eraser.

I opened it once before, a few years ago, to move the wiper to a fresh
bit of track. I'll open it again to clean the track.

Is the pencil eraser trick good enough, or would it benefit to use some
kinda cleaner?
