->> I use a pencil eraser. I alway hold the lens up and clean from underneath so the crumbs don't drop into the lens. Then I use blower to clean as well.
I have also use methanol dabbed on cloth and rub contacts.
Both work well to clean off a layer of oxidation that is often not visible. |

| ->> Instead of a regular pencil eraser, find yourself an eraser pencil made for old-time typewriters that used ribbons. They look like pencils but instead of lead inside it is filled with gritty eraser material. You sharpen/expose it in a pencil sharpener. This type eraser does a much better job in removing oxidation off contacts than a regular rubber eraser on a pencil. One typewriter pencil eraser will last you decades. |

| ->> I used a pencil eraser for many years (without issue) until a CPS rep told me they can damage the surface of the contacts on lenses and camera bodies. They recommend using a soft tissue dampened with isopropyl alcohol to clean the contacts. |

| ->> DeOxit is great. Spray a bit onto the tip of a q-tip. They have a type specifically for gold plated contacts also. |

->> David,
Glad you solved the problem. DeOxit products work very well, and are safe to use on the (very) thin gold coatings on the lens contacts. |

->> Sorry to here you have continued issues. One thing to keep in mind is that tele-converters and lens mounts on cameras take a lot of stress particularly when they are used with big lenses. For that reason, I only use one of my camera bodies with them. Once every two years I send my 400 2.8, 1.4 & 2.0 TC's, and the body I use to CPS together in the same box with written details on how they are used together. It's amazing what they find and have to clean, repair, and calibrate.
On the alternating years, I send my 300 2.8 and the same body in for a clean and check. I don't use TC's on my 300. I also send the camera body + 70-200 2.8 at the same time. That too has produced a few repair bills as well.
I looked through my invoices and it seems that Canon has replaced the camera body lens mount more often than anything else. They have only replaced the mount on a lens once.
I use to wait until something happened but stopped doing that about 6 years ago. What I do, however, is send equipment that is used more often to CPS and always provide details on how the equipment is used. That always seems to help the CPS folks out. |
