Quoted from Pinasco:
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 ?
Naptha is Naptha. It's not brand specific.
Use it to remove wax, especially 30 year old dried up wax.
It's used as a dewaxing agent for paint preparation.
For general cleaning you dont have to use it.
Re-waxing the playfield also removes the old wax. The solvents in the new wax do a good job of refreshing the wax.
Small quantities of naptha are commonly available and often sold as lighter fluid for the older Zippo style lighters.
The idea on older playfields is to use no water, or as little as possible. It can cause lifting and swelling of the wood.
Naptha is good for this as it doesnt hurt plastics and cleans metal.
But you have to apply new wax after using it as the old wax will be gone.
Regular waxing cleans the surface very well without the use of naptha.
Any light detergent like dish soap suds, ammonia free glass cleaner or automotive detailing compounds applied to a towel in small amounts, NOT directly to the surface, can be used for general wipe downs.
Followed by a dry towel to keep things as dry as possible.
