First; what a great thread !

As I understand it, Klean Strips WMP Naphtha would be the prime substance for normal cleaning when there is dirt that wont go away by vacuuming and soft dry towel swipes alone.

The problem for many of us non-US-pinheads is that the KS WMP Naphtha is not available and hard to buy due to shipping policies for flammable fluids.

Now a friend of mine who does car paint jobs said that he probably could get me a european brand of naphtha that has the same CAS-number (international classification for chemicals) as the Klean Strip WMP Naphtha.

Like the KS WMP this is also a hydrotreated light naphtha and has a solubility in water labeled as zero
( compared to less than 0,1 % in KS WMP). The KS WMP labels the pure naphtha content to 95-100 % and the substitute from my friend as 100 %.

So.....and I am no stranger or even hesitant to ask for the obvious or stupid: based on content and especially the fact that those two naphthas have the same CAS-number: it seem right to assume that the available substitute here would be as efficient and safe on the PF as the highly recommended Klean Strip WMP Naphtha ?

So much useful information and shared views here - really appreciated.

One short question on wax; the One Grand Blitz Carnauba Wax more precisely. How long do these jars with wax last in a small 3-5 collection with regular cleaning ? How long would you reckon that it is possible to store such a jar (unopened) without the wax becoming to old or dryed out ?

I thinking of ordering my first now, and should maybe get two while I'm at it.

I'm following the last exchange of thoughts here with huge interest (like a few hundred other pinheads I guess . )

@pinballinreno: on a dirty mylarcovered pf - would you rely more on naphta or Mist-n-Shine ? Will any of these substances mess with the Mylar so that it becomes miscolored or starts to come loose from the playfield ?
