Should I be wiping or removing contact cleaner?

Question

After testing a part (solenoid, sensor, etc) in an older vehicle, I have gotten in the habit of blasting the connection socket and plug with contact cleaner.
It's basically impossible to wipe the contact cleaner off in these locations, so I just re-plug the socket and move on.
Is this the right way to use an automotive contact cleaner, or do I need to wipe, rinse, or otherwise remove the cleaner after it's applied?
The cleaner itself has zero instructions on the bottle.

I've used CRC electrical cleaner for automotive use in the same manner you describe, on an old car, for years.  It has never done any damage.  I think the stuff evaporates without causing harm.
