Microfiber (always have a few in my bags, cases) works fine.

Topic: Using pencil eraser to clean Camera / Lens contacts? (Read 4468 times)
I think this is an "In a Pinch" solution.
It worked for my 7d and a 10-22mm I had. But I have to agree Clean them proper when you get home.
It's not an "in a pinch solution".... you can seriously damage the pins VERY easily.
The use of erasers to clean contacts goes with cleaning the contacts on printed circuit boards..... and you do remove the plating... clean them a few times and you can clearly see where the gold is worn away and the copper is showing. On the printed circuit board the contact is flat and easily plated.... not so on edges of materials... like pin ends. When you clean a circuit board connector the contact is over a much wider area than the tip of a pin so the pressure per square inch, and abrasiveness, is much less. The use of an eraser is destructive cleaning, I can't say it any plainer.
If you are spraying anything.... do not spray directly on the contacts as the solvent will also splash around either the camera body or the lens.... spray on something outside of the lens or the body and then use it to clean the contacts.
If you use a cleaner... you need to use something that will not leave a non-conductive residue. Things like WD40 will make electrical contact problems worse.
