Fotomiguel Posted January 20, 2007 Share #1 Â Posted January 20, 2007 Advertisement (gone after registration) Hello! I was trying to clean the dust on the sensor with just a bit of air. I used the air pression "Tetenal" recomended by Leica. In one of the tries the Tetenal spread some cold liquid. I did it without removing the bottle. Now I have marks on the sensor. Is this going to be permanet? Should I clean it with wet swab? Should I leave it and send the M8 to Solms? Thank you very much! Link to post Share on other sites More sharing options...

Shootist Posted January 20, 2007 Share #2 Â Posted January 20, 2007 Just what is Pression Tetenal?? Is this a bulb blower like a Rocket blower?? In any event get a sensor cleaning kit and do a wet cleaning of the sensor. I believe there are instructions for this in the M8 manual. Link to post Share on other sites More sharing options...
marknorton Posted January 20, 2007 Share #3 Â Posted January 20, 2007 Tetenal is a can of compressed air and the deposit is presumably the propellent. The danger is that leaving it on the sensor will etch into the cover glass or its coating. I'd recommend you wet clean the sensor using a Sensor Swab and Eclipse cleaning fluid which will likely remove the propellent deposit. Â If the correct materials are not available, you need to decide which is better - to clean the sensor with something else or wait for the correct materials or send the camera away. Generally, the longer you leave it, the greater the chance of damage. Â Alternatives to Sensor Swabs/Eclipse would be lens cleaning tissues folded into a wad and attached with tape to a wooden tooth pick. If you don't have Eclipse (which contains methanol), you need a volatile organic solvent like lens cleaning fluid or, dare I say it, vodka. Do NOT using anything aggressive and just make the tissue damp, not wet. Â Most of all, I suggest you practice on a blank CD which will show you how well it works before you do it for real. Â Good Luck! Link to post Share on other sites More sharing options...

Thank you Mark! I think you are right! I was a bit scared at the begining, but with the Sensor Swabs/Eclipse will be fine. I incline the can a bit without noticing it. It's just a bit of propellent, as you said. I just learning how to do it properly. And I have no experience at all cleaning sensors. Thank you again.
