Hey Mike, I have used CRC electrical contact cleaner for years on electrical assemblies; you can find it at Home Depot and Lowes in the electrical supplies section. Another "solution" is Everclear, available from your local gun & beverage store, at least the ones' I know in Fallon, Nevada... . Regards, Edd Dec 24, 2011 at 10:33 PM

Think I have heard not to use it on contacts. You probably heard it from a contact cleaner salesman. Seriously, I've been using the eraser end of a pencil for battery and lens contacts for years; never had a problem. I just go gently, and I break out the contact cleaner if it's really bad.

chas Offline • • • Upload & Sell: Off p.1 #10 · Clean contacts? From the school of "If it ain't broke....", do you clean your contracts only after you have had an error occur, or just as a routine maintenance process? Having owned Canon gear for over 8 years, I have never cleaned contacts. Dec 26, 2011 at 02:12 PM

Ben Horne Offline • • • • • • Upload & Sell: On p.1 #11 · Clean contacts? If you guys are cleaning the contacts just for the sake of cleaning the contacts... it really isn't necessary. I would only clean them if you are having a problem such as a corroded battery in a flash, or something along those lines. I think more photographers damage their equipment by overzealous cleaning than other common causes. Dec 26, 2011 at 04:27 PM

I think more photographers damage their equipment by overzealous cleaning than other common causes. "If it ain't broke don't fix it" works for some folk, "An ounce of prevention is worth a pound of cure" works for others. I look at my contacts every time I change a lens or a battery. If I see any black or green where I should see only silver or gold, I clean it; if I don't, I don't. Dec 26, 2011 at 06:47 PM

scalesusa Offline • • • • Upload & Sell: Off p.1 #13 · Clean contacts? The contacts are gold plated, and do not ozidize. The "wiping" action as you twist a lens to install it will almost always wipe away any light dirt or oil. Unless you are in a very dirty / oily environment, cleaning the contacts only serves to wear off the gold plating, and then you really will need to clean corrosion away. If you must clean them, use a soft non-abrasive cloth and alcohol or a non-abrasive contact cleaner. I've had dozens of lenses and many camera bodies over the past 15 years and never needed to clean the contacts. Dec 26, 2011 at 06:56 PM
