Use your lens cleaning supplies, you don't want to scratch the contacts and remove the gold plating. There shouldn't be any stubborn oxides since they are a gold alloy.
Yeah, just a little rubbing alcohol on a q-tip, not soaking wet. Gentle circular motion swiping the contacts. Use one wet then a gentle cleaning with a dry one, maybe breath a little on the contacts so condensation forms to help remove the last water soluble contaminants. I use this procedure on microscope optics and it works well.
You mean the contacts of the body,wich you see when you remove the lens? ...I don`t think we should worry about them,unless the camera is getting old,or having issues with it.
I would be more curious of how you clean that inner-lense ,from the body.I won`t dare touching it,and my camera has some automatic-dust-removal-e.m.p.-shockwave-thing,but still...
@indiannie_jones@spaceman yeah, i have some old lenses that aren't working with my camera..when i put them on, it gives me an "error, faulty contact between camera and lens" message, so i looked it up, and my manual told me to clean the contacts on the lens. haha, it had never really crossed my mind, so i had a total Aha! moment. i feel like i'm a bad camera owner for not knowing about that, but we all have to start somewhere. :)

Yeah,but if cleaning doesn`t help,you should check out the lens,it may have some other internal problem,I dont know. .....or just throw it all in the washin` machine and let it spin! :)
lighter fluid also works... I am not joking... it does... be very very very very gental... if you rub the gold off which is only atoms thick... if it rubs off you will need to clean very often!
@eyebrows think when are they exposed? When the lens is off the camera... dust and grease(the bad guys here) build up well the lens sits ideal, un protected... after 6-months... or a few years enough gunk could build up... by no means a day to day thing...
Contact cleaning really shouldn't need to be done on a regular basis. The quarter turn movement of installing and removing a lens is generally enough to keep the contacts clean.
However rubbing, or Isopropyl, alcohol can leave a residue behind. If you can get some methyl alcohol that is best. Another way that works very well is a soft eraser like on the back end of a pencil. Very lightly erase the contacts and they will get really clean. Do it with the face of the camera facing downward so any crumbs don't accidentally get inside the camera. Same with lens contacts. A light brushing with a very soft brush can help remove any crumbs too.
This is not something that needs to be done with any regularity. Just as the need arises or after some rough conditions (salt air, etc).

I should probably not mention that my method of cleaning contacts on lenses and flashes is to wipe them on my shirt...
