Barry Clemmons Photography Posted April 7, 2009 Share Posted April 7, 2009 <p>I am trying to put together a camera maintenance kit to take with me when I travel. Most of us at one time or another have had issues with the contacts between lens and camera body. Does anyone know of a felt tip pen type product that contains alcohol for cleaning electrical contacts? It needs to be small to take up as little room as possible in my bag.<br> Barry Clemmons</p> Link to comment Share on other sites More sharing options...
leicaglow Posted April 7, 2009 Share Posted April 7, 2009 <p>Hi Barry, A friend of mine who worked for Nikon told me to use a pencil with a rubber eraser. I carry a shortened one in my bag.</p> Link to comment Share on other sites More sharing options...

Barry Clemmons Photography Posted April 7, 2009 Author Share Posted April 7, 2009 <p>Michael and Lil, thanks for the responses. I can't believe I didn't think of using an eraser, and I am going to check out the DeoxIT Power Booster Pen online as well. <br> Barry</p> Link to comment Share on other sites More sharing options...
Ed_Ingold Posted April 7, 2009 Share Posted April 7, 2009 <p>I use lens tissue and lens cleaning fluid. Alcohol would work too, but on a tissue rather than the contacts directly. Don't touch them with anything abrasive.</p> <p>The contacts are gold plated because it doesn't oxidize, making it more reliable for low voltage signals than less noble metals. A pencil eraser contains pumice, and will cut through the gold instantly. You will make a career out of cleaning them ever after. Using erasers harks from an era 40 years ago when contacts were tin (solder) plated or brass.</p> Link to comment Share on other sites More sharing options...
liljuddakalilknyttphotogra Posted April 7, 2009 Share Posted April 7, 2009 <p>Somewhere recently I read not to use an eraser that that's bad. But I may be wrong in that...<br> Lil :-)</p> Link to comment Share on other sites More sharing options...
johnw63 Posted April 8, 2009 Share Posted April 8, 2009 <p>What about those soft white erasers that come as long as a pencil ?</p> Link to comment Share on other sites More sharing options...
Hector Javkin Posted April 8, 2009 Share Posted April 8, 2009 <p>I had used pencil erasers from time to time, with success, and had recommended their use, until someone pointed out a problem <a href="00Ouxs">in this photo.net thread</a> . I believe the criticism in that thread. The eraser could improve the contact temporarily but then cause problems later on.</p> Link to comment Share on other sites More sharing options...
james_symington1 Posted April 8, 2009 Share Posted April 8, 2009 <p>In 25+ years of taking photos I have never found a situation where lightly rubbing contacts with a clean handkerchief wasn't sufficient to resolve issues with them without introducing any other substance.</p> Link to comment Share on other sites More sharing options...
john_lynch5 Posted April 8, 2009 Share Posted April 8, 2009 I used a pencil eraser for years to clean the battery contacts in my manual cameras. Then I found a battery contact cleaner at a camera store. It looks like a mechanical pencil and has a stiff brush (probably nylon) that retracts. This worked better than the eraser. However, when I got my Canon EOS, I didn't think that rubbing those contacts on the lens and mount would be a good idea (I guess I was correct from the info above). I went to an electronics store (Fry's) and found "MG Chemicals Super Contact Cleaner". This stuff is great. It looks like a small marker. Just gently apply it to the contacts with just enough rubbing to get on them and the contacts are clean. Link to comment Share on other sites More sharing options...

lex_jenkins Posted April 10, 2009 Share Posted April 10, 2009 <p>Please, read that <a href="00Ouxs">earlier thread</a> Hector linked to. Using erasers to routinely clean contacts is a bad idea. At the very least, pencil erasers will leave a gummy residue on the contacts, and the little niblets that come off the erasers may get inside the camera and cause problems.</p> <p>At worst, they may damage the contacts. Virtually all contemporary contacts are plated and virtually resistant to serious oxidation. Any oxidation can be easily wiped off with a cotton swab or bit of lens tissue moistened with alcohol. But scrubbing with an eraser could damage the plated contacts and lead to a downward spiral of more and more serious oxidation problems.</p> <p>In more than four years with my D2H, various AF and AF-S Nikkors, SB-800 and SC-29, in all kinds of weather, I have never needed to clean the contacts. The one time I had a problem that might have seemed like a dirty contact it turned out to be a component failure (repaired under warranty by Nikon).</p> <p>I may have gently swabbed the contacts once a year, at most, but have never experienced a problem that was due to intermittent contact failure.</p> Link to comment Share on other sites More sharing options...
