Quoted from Velluminous:So quick question... What should I use to clean/wax the plastics and playfield?
Obviously there's some differences between a 1987 machine and something like a new Stern; What's good for one may not be good for the other. I see a lot of people talking about Novus 2 to clean and 1 to wax/polish (particularly for NEWER pins) but want to be sure that something like that would be safe (not stripping away paint or coating) because it's an older machine.
Depends on how dirty we are talking.
For a dirty machine, I like to start with naptha. It is good to break down old wax, and also remove dirt. I try to lift the dirt away as much as possible.
I'll then go to Novus2 as a polish, and go over the PF.
That's really good enough. Wax is a preference, I generally like to apply a light carnauba as I find it increases the speed of the machine.

I generally reserve Novus1 for heavy CC PFs, since it is has a lot of water in it... but TBH,. it's probably fine as well for quick cleans.
I don't have experience with any other polishes, I've used this product on machines from the 1960s to 2019 with no issue.
Many people will use some alcohol as well, generally this is ok.. but I have had some varnishes react to it, so I prefer naptha over it. If unsure, always best to test an area under the apron etc.
