[HUG ] Re: Cleaning the Mirror

Believe me, I wasn't going to try... ;-)
In fact I am not even sure that I have the guts to put collodion on my camera's mirror...
The Einstein brain thing was clearly tongue in cheek. I just wanted to draw the attention to the Wikipedia article, which describes the method suggested by Bob Kiss as being used to clean delicate surfaces such as telescope mirrors.

I'd like to add my 2 cents to this collodion stuff and Einstein's brain. I was in the business of doing this kind of work for many years (I am, or was, a pathologist). The story about how Einstein's brain was mishandled, including this use of collodion, is well known among "brain people". Collodion has many uses in medicine and other areas. Its use for mirror cleaning sounds reasonable to me, and I know it has been used successfully for this purpose by skilled people. But its use to preserve brains should be eschewed.
Do not inject collodion into your skull! It will not do good things to your brain. Trust me.

According to the Wikipedia "Collodion was also used by pathologist
Thomas Stoltz Harvey to preserve Einstein's brain in 1955".
If it was safe to use on Einstein's brain, surely it cannot harm a
Hasselblad mirror...


Well.. Einstein was already dead so..

:)
By the way, they also mention its use for cleaning optics. They describe an "improved" version of Bob's method, which consists in applying two layers of collodion with a piece of thin cloth in between to facilitate 
the removal.
