here are a couple of links that speak to the use of collodion usp for mirror cleaning:
http://www1.tecs.com/oldscope/atspages/techtips.htm
http://www.ghg.net/cshaw/clean.htm
I am not so much interested in this for mirror cleaning as I am for dust particle removal from CCD gear, notably filters and the front window of the camera. I bought a pint some time back but have not used it yet, so I cannot speak to the effectiveness but the operational concept is appealing to me.

but leaves the mirror coating behind.
I bought a can of the stuff but have yet to use it. Gallande Chemical
sells it as well as Acetone, Methanol and other such solvents in gallon sizes
in the reagent grade.

the
cleaning of coated glass lenses, rather than aluminized mirrors. The
principles _may_ be the same. That's what I'm trying to find out. Should
acetone be used to dry a mirror? Damaging an eyepiece would be
unfortunate,
but scratching the mirror could put me on the sidelines for months.
