Getting an error code to clean contacts. Anyone have luck doing it yourself? What did you use?
I’ve tried in the past but never had positive results. Cleaned both lens and body contact. Wound up sending to Canon. Now a friend is asking.
Thanks!

Did it work on your current digital camera?
I’ve tried that.
Didn’t work for me and now have read the contacts aren’t like they were in the old days and NOT to use erasers.

Electrical contact cleaner applied with a non-abrasive cloth. Available on Amazon from multiple sources. Make sure to get one without lubricant.

Or alcohol swabs (like before you get stuck).
I open the packet, stick a Q-tip in, squeeze to soak the Q-tip, then gently wipe the contacts and dry. Do both the lens and camera.

I'd NEVER use a pencil eraser on the contacts as they only have microns of gold plating. A pencil eraser is too abrasive.

Do not recommend a red pencil eraser as they are abrasive. It will clean them just fine, but roughs up the surface inviting more corrosion. I suggest starting with alcohol wipes, and don't be shy with rubbing, just don't apply too much pressure - I know, its by feel. You don't want to push so hard you bend something. If that doesn't work, try a white non-abrasive eraser. If that doesn't do it, its try to send it in.

If cleaning the contacts doesn't work, it's probably something else.

For the love of Ansel, don’t use an eraser! You will either put static loving shards into your lens or body, or do the job in a way that takes off too much material.

If it doesn’t come off with microfiber and alcohol you are going to need a professional cleaning anyway.

Your choice. I'm just telling you what I have used to remove oxidation from the gold contacts. Furthermore, I am skeptical of individuals that make unsubstantiated claims that a rubber eraser will damage the contacts. But as I said, it's your choice.

Unsubstantiated? I spent some time online a couple years ago and several reputable sources are readily available that advised against using an eraser for the stated reasons.

Gold does not oxidize.
It just would get dirty.

never use an eraser!! the little particles can get inside of the camera and cause more problems.micro fiber with some 70percent isopropyl alcohol will do the trick
