Is it safe to use WD40 as a switch (or potentiometer) cleaner on
circuit boards and in electronic equipment?

I know that you can get the proper aerosol spray cans of switch
cleaner but if I find myself without one of those then can I use
WD40?

Personally I would guess it is not OK as I figure there is always a
thin layer of oil but several people I have spoken to say that they
use WD40 all the time.

Any views on this?


WD40 is a mixture of kerosene and light spindle oil, not much good
for
cleaning since it doesn't evaporate at any rate that would leave a dry
surface in your life time.

And oil turns to varnish over a longer period of time.
