Also, some furnaces draw combustion air from outdoors. If spraying outdoors, don't do it near the intake. At least I don't need to say "don't ask how I know this", because I didn't learn it the hard way.
The number of unknown hazards with these products is astounding. I had never thought about the possibility of sparking a fire as a result of cleaning the track. Thanks for the heads-up.
Some of these solvents listed are real dangerous. The vapors form some of the solvent discussed will "travel" along a horizontal surface finding an ignition source. An example could be using one of these solvents to clean parts in an open tray, set to the side and uncovered. Now one plugs in a small hand held soldering iron to a nearby outlet. A small arc occurs in the outlet and a resulting flash occurs, followed by the remaining fluid in the dish burring.
Same thing could happen with a rag with enough solvent applied.
Other solvents may be a bit more volatile and not concentrate near the surface and therefore be below the ignition point at some distance. They will smell. Please be careful from both a fire hazard and health hazard.
