Body grip brassing

[c22w1]

Any body have any ideas how to get the CF card door back to a nice matt finish and remove the brassing/polishing, shiny effect through handling at all, other than replace the door? Its not as strait forward as you would imagine.

Have you tried alcohol swabs? A lot of the patina is just grease from your fingers.

Try WD40 sprayed onto a cloth - not the camera - it is great at taking the patina from lens grips and it is non abrasive.

Thanks for the responses but its not a build up of anything its the finish that has worn away through use and has become polished. I want to try to dull it down again to give a matt finish once again.
Thanks
