sfokevin Posted July 18, 2009 Share #41 Posted July 18, 2009 Advertisement (gone after registration) That's very interesting Michael - thanks. That might explain why my dealer just shrugged and said 'we use the corner of a cleaning cloth or anything we have to hand - no problem' - all very un-nasa like! I'm tempted to breath on it and use the corner of some bog roll just to prove or unprove the point that all this super-technicality could be marketing snake oil! :-)) Julian before attempting the breath method I would highly recommend a large sip of Natured Alcohol that is at least 7 years old...

jaapv Posted July 19, 2009 Share #42 Posted July 19, 2009 I understand the reason that Eclipse fluid is SPECIFICALLY banded on aircraft, either in the cabin or in checked luggage is that is extremely flammable. (or more likely upsets the TSA because it sets their bomb sensors off). They will remove it from your checked luggage if they find it. Just put it in your toilet bag in your checked luggage. There is no record of any of it ever been removed. Link to post Share on other sites More sharing options...
gwelland Posted July 19, 2009 Share #43 Posted July 19, 2009 Just put it in your toilet bag in your checked luggage. There is no record of any of it ever been removed. You may get away with it but if the TSA read the label which states in big read letters Caution: Flammable then it will be removed. Even stores & the manufacturer can only ship the stuff by ground so make of that what you will. Like I said though - you may get away with it or you may simply get it removed. Your choice.

Wilson This is kind of OT but ... as a weekly frequent flyer don't get me started with the idiocy of many of these policies and their inconsistent application. Common sense doesn't always seem to be a criteria for some of this stuff, plus it's also partially driven by 'retail' considerations too. Grrr ....

SJP Posted July 19, 2009 Share #46 Posted July 19, 2009 The breath of hot air is not quite so stupid as (some) people may think. What you get is a freshly deposited layer of distilled water. Distilled water is one of the strongest solvents you could imagine especially for polar compounds. IPA (iso-propyl-alcohol) is less polar than water making it more suitable for 'oily' apolar contaminants. So the breath of hot air should not do any harm, OTHOH it should not help too much with the grease. If you use IPA and tissue the procedure is: - fold tissue to the required width for a clean swipe - grip with plastic pincette (or metal if you have strong nerves) - soak with IPA and shake/flick out the surplus (repeat 1-2 times) - wait to get the right level of 'dampness' - short wait => wet, long wait => nearly dry - swab the sensor If you use cotton swabs then you need to get some practice in swiping so that you do not leave any stripes, again soak and shake/flick out the suplus. This removes any residue from the tissue/cotton. EDIT: IPA is less flammable than ethanol (AKA perfume). Link to post Share on other sites More sharing options...
Nicoleica Posted July 19, 2009 Share #47 Posted July 19, 2009 Advertisement (gone after registration) Distilled water is one of the strongest solvents you could imagine especially for polar compounds. That's why water is called the 'Universal solvent'. Link to post Share on other sites More sharing options...
SJP Posted July 19, 2009 Share #48 Posted July 19, 2009 That's why water is called the 'Universal solvent'. Yep, to put into context dissolving of common salt in water is a pretty amazing phenomenon. The bonds in salt (NaCl) are pretty strong and it needs to be heated to 1465 °C for it to boil. The interaction with water is so strong that the Na+ and Cl- get separated at room temperture.

Jeff S Posted July 20, 2009 Share #49 Posted July 20, 2009 Someone might have already mentioned this, but I happened to be looking through some old LFI articles, and there's one in the 7/2007 issue regarding cleaning M8 (and DMR) sensors. FWIW, it says "Leica's customer service uses nothing fancy but a homemade plastic spatula, dry optical cloths and isopropyl alcohol," and explains how you can do the same. (It also describes air blowing first, etc.) However, the technicians there know what they're doing, and I assume use pure grade Isopropyl, as others here caution. For me, I'll stick with swabs and fluids by manufacturers mentioned here, but heed the warnings in the article about not using the B shutter setting (yikes), not using too much pressure, etc. (Or, drop by my friendly and always helpful local dealer when not on the road).

jaapv Posted July 20, 2009 Share #50 Posted July 20, 2009 I think the coating on the M8 sensor glass is not the same - and not as resistant- as that on the DMR. Link to post Share on other sites More sharing options...
