According to the SDS sheet, its ingredients are Naphtha (petroloeum) hydrotreated light 30-60%, Propan-2-ol (IPA) 10-30%, and Xylene 5-10%. It also contains Propane 10-30%, Butane 5-10%, and Isobutane 1-5% which I assume, quite possible wrongly in view of my utter lack of scientific knowledge, are propellants. As the main ingredient appears to be petroleum, and as propanol and xylene are excellent cleaners, I wonder if this product would also be a suitable non-polar cleaning fluid.
I reckon such a complex brew would need a test similar to what I am planning......Heptane already on order!
I prefer to KISS the issue and use the least ingredients that do the job.
