Corrosion on the 20D lens mount!

[pingwin]

Hi:

I just performed my first sensor swipe, still got some dust but as I was cleening the sensor I noticed corrosion on the lens mount. I did a search on this subject and there is a lot about how to protect your camera from corrosion.
My question: is there anything I can do to clean (remove) corrosion of my lens mount.
I tried clining with some alcohol but I can still see a very little spot on the ring and lots of corrosion around the mount going inside the camera body.

Please help!!!!!!!!!!!!!!!!!!!!:o

Are you sure that is corrosion? I think lens mount is made of stainless steel. Maybe its just dirt?

I can't send a picture of this but I took a good look at this and it does look like a coorosion-rust.
I swiped most of it with lens cleaner (after I read that destiled water is best:o )
and most of that residue I was able to remove. There is one spot that I can't get rid off so that's why I think that this is corrosion. I can also see it going down into the camera body, I think this is some light stuff there but there is no chance to clean it without opening the camera.
I just contacted Canon service rep. ant they said that I have to send my camera for an estimate on repair as warranty do not apparently cover this kind of "defects".

Anybody with the same experience???

I would think putting a corosion blocker and cleaner on it like WD40 or Houdini would clean it and prevent it. I would swab it on lightly with power off ofcourse. Stop putting water on it, to include distilled water.

Whatever you do, do not put lubricants on the lens mount as it could end up on the sensor due to vapourization or when you use a blower to clean the sensor. If in doubt, let Canon look at it. It may cost you money to get it sorted, but that is better than having it sent back to get WD40 off the sensor, mirror and elsewhere.

I go with Ken, that and the fact you have all those contacts to keep clean.

Excuse me for the confusion, I thought I said swab it on lightly, not spray it on librally. But sure sending it to Canon would always be your safest bet.Whatever you do, do not put lubricants on the lens mount as it could end up on the sensor due to vapourization or when you use a blower to clean the sensor.

Thank you for taking time to help me out! I was thinking about WD40 or something similar but KennyG; you are right. I don't think that this can go under warranty repair do.

I was a corrosion specialist for a few years for the U.S.Navy and you will find that many products release corrosive vapors.(i.e. swimming pool cleaning acid transported and spilled in your car)or even plactics. After you get your camera checked out, be sure to look aroud where you are storing and using it for any items that might be a cause. Just a thought.
