First clean up, advice needed

[tekbow]

Hi guys, picked up a Puma 52 on here a few weeks back, Fantastic shaver, was a little watermakred however. Not that this was a problem, as there was no rust or pitting. The pic of it is here:

hard to see the watermarking (thats how slight it is)

So i figured today that i have to learn to clean sometime, so i went and got some autosol and started to work on it, making sure to stay away from the edge.

Started with a Q-tip rubbing it in, and the cream was turning black so definitely lifting something. but had marks left, so moved up to a Microfibre cloth and a little more autosol (still keeping the cream away from the edge) still turning black, but having a hard time removing the staining. Now as this is my first time i have to ask, is using autosol usually quick and fast or does it require a lot of work? i've been at it for 30 mins now. Do i need to move up to sand paper maybe?

also, these have the original scales and would like to keep them that way, is autosol detrimental to plastic? i'm keeping the cream well away just in case but would like to get at the pivot with a Q-tip or floss. Is this something to leave for when the scales are off?

cheers
