As this thread proves, whatever works for you is fine. A few points however:
* Many, many people use canned-air on optics, if it was as lethal as described herein, it would have been banned a long time ago and not sold in Staples. If your knees buckle and you get all quivery at the thought of using it, then don't. But don't come here to scare the living bejesus out of those reading this. A constructive post would have been to post a link to the MSDS and not say another word. Give us the information then let us make a sane, rational decision. Most of us do not have access nor can afford a filtered air compressor as found in labs, but for over a decade we've been doing pretty good with the low-tech tools at our disposal including swabs and air and brushes.
For cryin' out loud, there is a well-known company that sells sensor cleaning products with a website that maintains Eclipse will bore a hole in your sensor and through the floor and all the way to the other side of the planet. They also say that just being in the same room with methanol will cause one to go insane, get cancer and start hallucinating. Do you believe everything you read? If so, we are truly doomed.
Sorry. I hate to flame the fire, but come on..
I am gonna "say another word" despite your CLEARLY true and ground breaking reasons/proof that this is a great product to use on your very expensive optics and optical coatings
Umm, so because they sell canned air at Staples, that automatically means that it is perfectly safe to use on OPTICS. that IS the topic at hand....when it is clearly marketed for electronics, etc..and is "not banned", so it must work well..
They also sell acetone, bleach, and many other chemicals in stores, so clearly, "BECAUSE THEY SELL THEM", it MUST be safe to just drown your lenses in bleach to get them clean...
I mean, that is the exact same "logic" you are using...
Someone HAS already posted some MSDS info about canned air and the chemicals(NONE of which are actual "air"!!), and I am not BLINDLY making an irrational decision or saying that it will burn a whole in your optics.
I have in fact worked with optics, optical coatings, and highly sensitive electronics(including cleaning and maintaining optics and electronics) for over 10 years and giving my PROFESSIONAL opinion on using canned air for THIS EXACT purpose.
And I am not trying to scare the bejesus out of anyone...merely giving MY opinion and experiences after learning this lesson the hard way.
If you want to sit there and give people some random 'freedom to not believe any/everything you read' crap based on some really ridiculous reasons like; "it would have been banned from Staples years ago", or because "we have been doing pretty good with 'low-tech' tools"...pretty sure an air compressor is VERY low tech. you may not have one..but I am willing to bet one of your friends/family/neighbors do..
Even better would be to just forego the canned air and use a bulb blower (which was my original/constant message/point) on even some of the most sticky and annoying dust spots...IF that doesnt work, along with a good wet clean with any of the recommended products listed thus far, then maybe look at borrowing or using something with some more strength..
If you/anyone thinks that canned air is that product to use, please, do not let me "stop you"(as if I could)
most people(kids) buy canned air for only one reason..to get high.lol
And honestly, in this specific topic, that may be all it is good for. killing brain cells. OR blowing some hair/dust off of your keyboard..that is also a good purpose for this product.
And yes. I believe EVERYthing I read
And everyone else does too, obviously, since apparently my opinion in the thread is scaring the bejesus out of people and making them think that just being in the room with canned air will kill them, or their optics/optical coatings.
And we are doomed regardless, no matter what this thread implies..seeing how people continue to believe in things like "global warming" or "climate shift", and using canned air on highly sensitive optical surfaces.
Go ahead. use it on your most expensive L lenses and have fun. especially a nice new 85L II or even better the 24 TS-E II with "Sub-wavelength structure and super-spectra coatings"...would love to see what the chemicals in canned air would do to them.
It is your life/money/gear/opinion, do what you want! not trying to take that from you/anyone...just giving my opinion on the topic at hand......unless you have a problem with that..? dont want to scare the bejesus out of anyone for no apparent reason..
Alright. done. no more "flaming"(and yes, I will leave that open for you if you want to use it in some 'very clever' way)
