Hi Guys,

I started on the playfield today.. I used metho and gently rubbed off a lot of the gunk that was caked on it. However, even though i took heaps of crap off it, it still remains dirty and im tooo scared to rub any harder. Whats the next step?

Do i try metho again?
Do i spray it on and leave it overnight? 
Do i move to novus?
Do i try magic eraser?
Any other product i should try before i get into magic eraser?

Sorry about all the questions in 1 post but not sure what to do

It does look heaps better though but i want perfection and its not even close
