Zeiss lens wipes. Box of 100 for $5 when on sale at walmart.
Excellent choice for camera gear, glasses, computer screens, and many other uses.
I have packs of them in my bags, briefcases, glove compartments, and anywhere else I can stash them.
Believe Me IT Works..................
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.
Use a Photosol eWipe (or a PecPad wet slightly with 100% isopropyl or methyl alcohol).
Be extremely gentle! The spring-loaded pins snap off easily.
The usual culprit is oil, grease, or dust.
It helps to keep a rear cap on your lenses when they’re not in use, and to keep them in your case.
Third party lenses are more likely to need their pins cleaned than OEM lenses.
Rubber eraser from a pencil.
This is what Canon recommends..... AND I THINK IS WRONG.
Often the problem with lens contacts is due to oils interrupting the tiny voltages being used for the lens and camera to communicate with each other. It might be oils from the manufacturing process or finger oils or lube from internal camera parts that somehow got on there or whatever.
The problem with using pencil erasers is that they're made from vegetable oil. An eraser won't clean off any oils on the contacts... might even add more!
I recommend using a clean, lint free rag lightly dampened with a few drops of isopropyl alcohol and carefully wiping the contacts with that. "Rubbing" alcohol is fine (cheap & easy to find). That usually does the trick.
DO NOT use ink erasers or anything else that's abrasive on the contacts. They're gold plated and you don't want to damage that.
Gold is an ideal conductor of small voltages. Gold doesn't oxidize, so should never need any sort of the stronger chemical cleaning that some other types of metal do.
Also, pencil erasers can shed particles and I'd hate to see any of those get into the shutter & mirror mechanisms of the camera.
Isopropyl alchohol and rubbing alcohol are very different beasts. Isopropyl alcohol is preferred for cleaning electronic equipment, primarily because it is less likely to damage rubber or plastic parts. It has degreasing and cleaning properties, but does not have the drying effects of rubbing alcohol. There are a couple of things to watch out for, though. It will remove desirable lubricant from moving parts, and it (isopropyl alcohol) evaporates quite a bit more slowly than rubbing alcohol. Make sure that it is all removed or evaporated before reassembling the lens to the camera. And it is a pretty strong solvent...radio shops use it to remove identification paint from equipment. Finally...common drugstore isopropyl alcohol is generally 70% alcohol. The remainder (almost a third) is water. This solution is not nearly as desirable as 90% IA.
"Rubbing" alcohol is fine (cheap & easy to find). That usually does the trick.
DO NOT USE RUBBING ALCOHOL... it has an oil additive that reduces friction for 'rubbing'.
Yep, saw and posted that first one from LensProToGO. Thanks anyway.

Which is yours and which is Canon's opinion?
I can't tell what you think is wrong.
After being in the electronics industry for many years, I've learn that the contacts or leads on many of the PC boards become oxidized. cleaning them with alcohol is one way to correct the issues. But in some cases if the leads are oxidized or even showing signs of corrosion. a very fine grade of sandpaper of extra fine emory board would be used. If the corrosion has went deeper into the lens or contacts, this would require a complete tear down of the lens to access the issue. I recall once that we had to re-coat the leads on several PC boards with solder. Not saying you should do this. but cleaning or light sanding would be the first step.
Anybody that would use any kind of abrasive on lens or camera contacts needs his/her head examined. What a bunch of garbage.
