+Graham Posted March 13, 2015 Share Posted March 13, 2015 Calling all you chemists out there. I have aquired a bottle of cleaning soloution from work. It is the stuff we use to clean our glasses with. It is iso something alcahol. Will this damage the coatings on the optics. I got it mainly to clean the chip on the 350 d.

Sheila Posted March 13, 2015 Share Posted March 13, 2015 ISO propyl alcohol I would guess or another name is propan-2-ol This is the stuff in use to clean my filters And is ok for that. Cannot comment on Dslr chips though. Never done that Ibbo is best to ask on that one as he has done them Sheila Check this is the exact name of the stuff you have Link to comment Share on other sites More sharing options...
red dwalf Posted March 13, 2015 Share Posted March 13, 2015 not sure about the stuff you use but i use the wonder fluid from baader, works very well and dries smear free. Link to comment Share on other sites More sharing options...
Guest Eddy Posted March 13, 2015 Share Posted March 13, 2015 I used a chip cleaner on mine, its like a sticky pad thing that doesn't leave residue but picks up dirt, I can't image isopropyl will damage it, its protected by glass right? Link to comment Share on other sites More sharing options...
+Graham Posted March 13, 2015 Author Share Posted March 13, 2015 Thanks folks. I will check on exact name when i get home. No eddy no glass on my chip. Link to comment Share on other sites More sharing options...

Orion Posted March 14, 2015 Share Posted March 14, 2015 It's likely to be Isopropanol, not isoproponal. Infact the CAS Chemical Abstracts Number confirms it is Isopropanol. Isopropanol is the same as isopropyl alcohol, an alcohol that is commonly found in the more expensive car de-icers ( cheaper ones and more volatile contain methanol and water). It is used to clean tape heads as well. The pure alcohol should be ok on glass optics. I'm not certain about on ccd chip glasses. I once cleaned a window of a ccd camera using absolute alcohol and teasted out lens tissue - rolled then torn then teased out and twirled then dipped in the alcohol, and very gently pulled over (not rubbed) the glass. This was to remove a spot stain that appeared on photomicrographic images. It did the trick. I would be interested to know if that technique (and absolute alcohol = ethanol, or pure isopropanol) would be ok on dslr sensors - which I don't think they are covered with glass protection, though unsure. I'm really a novice on the digital equipment, but I am a chemist. I note the hazardous ingredients of the Uvex. It is assummed the balance is water. Im surprised that the surfactants dont leave residues since they are normally soapy non volatille substances, but they may run off to the edges as a result of low surface tension - the principle of washing film negatives and slides. Isopropanol is ok for cleaning mirrors. Link to comment Share on other sites More sharing options...
Sheila Posted March 14, 2015 Share Posted March 14, 2015 mine does not indicate anything put pure iso propyl alcohol, no blends of additives to leave on surface, not sure about that one really. i cleaned only optics and filters with it sheila Link to comment Share on other sites More sharing options...
+Graham Posted March 14, 2015 Author Share Posted March 14, 2015 Thanks again folks. I bit the bullet today and cleaned the front of the GT 81 as it was filthy mainly due I suspect to the number of coal fires around here and it has cleaned it a treat. I also cleaned the sensor on the 350 but have yet to test that out. Link to comment Share on other sites More sharing options...
Werisit Posted March 14, 2015 Share Posted March 14, 2015 (edited) I've cleaned the sensor on my Nikon dslr a couple of times, and an absolutely filthy sensor on an old Pentax, before giving it to my daughter, with the pads in Steve's link. They did a really good job. Edited March 14, 2015 by Werisit Link to comment Share on other sites More sharing options...
