I tend to agree with most of what you said Mike, especially the fear most
folks have thinking of cleaning their mirrors. However I do think it is better to
have water flow removing grime before you attempt to wipe the surface. And
I dont think that is being to over cautious. Like you I've had my scope a year
and a half and washed the mirror about four times, usually before I want to
seriously try some planetary imaging. And my mirror seem none the worst for
wear, you just have to take care in handling it. From mirror cell to vegie bowl
for me, and I avoid touching the surface with your fingers

Using distilled water you shouldn't have to absorb any remaining droplets or
use a puff brush. I just sit mine outside, preferably in a gently wind. I also
mark the mirror cell and side of the mirror itself so I can replace it the
same way it came out.

Just my thoughts
