Be careful with that stuff. Check the web for what you should not be using it on. It dilutes greases and oils. It can damage some plastics. It’s hydroscopic/hydrophilic (mixes with water). And it should not be used for joint pain relief as my father-in-law did (the solvents in it heat the skin, much like gasoline, and I suppose that can spell relief).
