Cleaning microscope mirrors
Any recommendations for cleaning the internal mirrors?
I´m happy with the film method, although I use cheaper alternatives than this ;-)

I use collodion scar fluid, but beware of Plastics because it seems to have some strong solvents.

Do you just paint it on, wait for it to dry and peel off?
The telescope guys clean their mirrors by washing with detergent and then dragging cotton wool pads over the surface and then rinsing with a 70:30 distilled water/isopropyl alcohol mix.
I can't take the mirrors out so this is not easy!
Would a buildup of dust just have the effect of reducing brightness or would it have an other optical effect? Loss of contrast etc?

yes that`s what I do, but before peeling off i blow out the surrounding area. I keep the film on as long as possible as a protector and dust shield.Andy Davies wrote:Do you just paint it on, wait for it to dry and peel off?
Of Course if you can rinse the mirror this would also be fine. Avoid mechanical stress on the mirror Surface since those coatings seem to be delicate and after a while the mirror could get some dull spots where you accidentally damaged the coating.
if the film does not come off completedly redo another film application. Glue a small piece of paper with some fluid to the boarder of the mirror and after drying use ithe dried paper as film zipper.

I have used Sensor-film to remove dust and water spots from my camera's sensor.
No idea if it will work for mirrors
Paint it on as a liquid, peel it off when dry.
price for 15mL was reasonable, likely all you would need
