Maybe someone could point out the disadvantages of
using it as a cleaner,
because I clean/protect everything with it, however I don't *lubricate*
Well, it's hydrocarbon-based, so it may attack some plastics and more
likely rubber [1]. Also, it will probably leave some deposit (thw waxy
part of the WD40) on the surface.
It depends what you want to clean with it. It's probably OK on most
computer cases, etc, but I wouldn't use it on my camera lens or the heads
of my RK05 :-)
[1] I once had to soak a beraring (the carriage bearing from a Sanders
700 printer (yes, it's on-topic)) in oil. This is a tubular part with a
broze bush at each end. Anyway, I tried putting a plastic bag over one
end, securing it with a rubber band. Then I filled the bearing with oil.
Enough oil got on the outside that about 30 seconds later the rubber
benad disintegrated, the bag came off, and the oil went all over the
bench. I tried a couple more times with the same result...
