Heh - I've read plenty of posts about Milwax & seems people either really love it or really hate it. RichyRich may I ask the genesis of (or underlying reason for) your question? If you are indeed RR you could afford many cleaners & get Cadbury to do the buffing for you.
Nice one ,Andypinboy
unfortunately Im still working on that 
{ my own Cadbury,that is}
I ask, because I just bought a pin and the playfield has some marks I cant get rid of.
It looks like just dirt that is worn in by dirty balls.
Ive tried Milwax,which is what I normally use,however,it is not getting rid of the marks.
Cheers
No matter what you try and use, if you don't allow for the cleaning solution to enter where the dirt is - you will never lift it out. Theres no magic magnetic attraction here.
ALL cleaning solutions work because the solution reaches the dirt.. loosens it and then you lift it out ( ME.. rag whatever).
ME works because its a super absorber and so will literally SUCK the now dirty solution out of the PF.. but as I have said many times... if the solution hasn't reached to the depth of the dirt, NOTHING will work... all you are doing is rubbing away artwork.
BUT!!! I hear you say... ME works if you rub it a bit... yes it does, but only because you have now pushed the solution down to the dirt... the rubbing to get there did a whole host of damage to your PF and was a pointless and damaging exercise.
