[AZ-Observing] Re: oh-oh... mirror cleaning time

I use dishwater soap in distilled water and gently clean the mirror by just
dragging a cotton swab around. The cotton I use is the sterile refined stuff 
that
has less chance of abrasive particles being in it. Then I add some Kodak
Photo-Flo 200 solution to distilled water and rinse of the mirror with the 
mirror
(as well as yourself) standing in a vertical position.  The water will film off
without hardly any droplets left over. Any that ramain are absorbed with tissue
paper. To make sure all soap residue is off you need to do a good job of rinsing
by dragging a cotton swab. The final rinse is without a cotton swab
