I need to clean the inside of the plastic gauge face to remove some oxidation. Does anybody know how to get just the plastic face off? Thanks

 

If they are like the 911's, then you have to remove the gauge, and pry around the edge of the metal ring on the outside with a tiny screw driver and eventually you can remove the ring, and the face...then you put it back together and press the ring back in place..

 

Ok...how do I properly remove the gauges? And would I have to remove the steering wheel?
