there are lots of WD40 products,
im sure there never used to be,i'm on about the original,bog standard ,wd40.
That's what happens when you're stupid enough to give your company the same name as your first product
* As I mentioned, there have been several previous 'discussions' along the lines of "spray your sensitive switch with WD40"... "don't be a moron!" when it turns out that the poor first poster was actually referring to WD40 switch cleaner (which appears more common in the US). I notice that the OP has posted an image of WD40 Silicone spray (which might be more common in Australia).
Personally I avoid the traditional WD40 because it is designed to leave a rust repellant film on surfaces, (and having Silicone spray around will contaminate your work area, switch contacts etc).
One of the other concoctions containing
IPA Ethanol is safest. I use meths because it is cheaper and more easily available (diy store) - I keep my good IPA for more critical tasks.
