For the record, you can always check the MSDS of each particular product to see exactly what is in it. "Ingredient Names" on the MSDS are ambiguous at best, so it's best to look up the "CAS Number" instead. Each chemical component is given a unique identifying number that can be used to cross reference other MSDS sheets, or to look up what exactly what the number corresponds to in a database.
I did some digging. Generally "VM&P" Naphtha from a hardware store or painting store is the "gold standard." It's what you'd want to use on your playfields. Looking up the MSDS for this particular product from Klean Strip shows the ingredient "Hydrotreated light naphtha" at a concentration of 95.0% to 100.0% (CAS Number: 64742-49-0).
Looking at Coleman Camp Fuel (White Gas), the MSDS states the ingredient as "Light Hydrotreated Distillate" at a concentration of 100%. This is technically naphtha, but not the same kind, as it has the CAS Number: 68410-97-9
Looking at Ronsonol Lighter Fluid, the MSDS States the main ingredient as "Aliphatic hydrocarbon,Hydrocarbons, C7-C9, n-alkanes, isoalkanes, cyclics" at a concentration of 100%, which is cryptic at best, HOWEVER, the CAS Number is 64742-49-0, which means that the product is chemically identical to Klean Strip's VM&P Naphtha.
Interestingly, Zippo's lighter fluid is actually a mixture of 70% "Light Hydrotreated Distillate" (CAS Number: 68410-97-9) AND 30% "Hydrotreated Light Naphtha" (CAS Number is 64742-49-0), which means it's a 70/30 mix of Coleman Camp Fuel and VM&P Naphtha.
Too lazy and didn't read all the nonsense above? In short, not all Naphthas are created equal. Kleen Strip VM&P Naphtha and Ronsonol Lighter Fluid are functionally and chemically identical in every way. So get whichever is available in your respective country/state. Coleman camp fuel, while technically naphtha, is not the same as the aforementioned products. It might be close enough to work, but it's chemically different. And Zippo lighter fluid is a mix of both coleman fuel and ronsonol fuel. Use at your own risk.
