: I have just obtained a secondhand mirror. The surface has a very small blemish but is basically sound but dusty. What is the best way of cleaning the dust off the surface ?

There is story in the July issue of either Astronomy or Sky an Tel. about optics cleaning. They basically say to rinse with water, wash with a mild detergent, rinse again and then rinse with distilled water. You should read that story to be sure.

I do remember a unique way to clean optics involving this sticky liquid. What you do is gently paint the liquid onto the optic surface and let it dry to a film. Then you gently peel the film off the optic along with the dirt. I saw this stuff at an astronomy club meeting many years ago. I do not know where to find it, but I will look around.
