progress is very slow..
But here is what happened;
1.Tried Alcohol without success
2.Alcohol + magic eraser no success
3.Tried leaving some sugar soap (watered down) on small parts of the playfield then wipe off and ME - no success
4. finally what started working - the missus bought me some sugar soap wipes which we folded up and squeezed and left on small parts of playfield for 10 mins. Came back to the playfield and scrubbed with the wipe until the watery residue was really dirty. Wiping off all excess moisture, then hit it with ME with it still be wet for lubrication.
Results arent too bad (my photography below makes it look better than it is) so i will rinse and repeat the above process (number 4.) and see how good i can get it. This is gonna take a long time :(
Here is a pic with ride hand side getting the treatment and the left side without.
