It is a good tool to clean the surface of cameras… not the lens!

WD-40

The product began from a search for a rust preventative solvent and de-
greaser to protect missile parts. WD-40 was created in 1953 by three
technicians at the San Diego Rocket Chemical Company. Its name comes
from the project that was to find a “water displacement” compound.
They were successful with the fortieth formulation, thus WD-40.

The Corvair Company bought it in bulk to protect their Atlas missile
parts. The workers were so pleased with the product, they began
smuggling (also known as “shrinkage” or “stealing”) it out to use at
home. The executives decided there might be a consumer market for it
and put it in aerosol cans. The rest, as they say, is history.

It is a carefully guarded recipe known only to four people. Only one
of them is the “brew master.” There are about 2.5 million gallons of
the stuff manufactured each year. It gets its distinctive smell from a
fragrance that is added to the brew. Ken East says there is nothing in
WD-40 that would hurt you.

box — duct tape and WD-40.   If it moves and it shouldn’t… tape
it.  If it doesn’t move and it should… WD-40.”
