photogem: I'm still having issue with the quoting thing I can't figure out how to just quote sections, I tried highlighting the item I want quoted yet it appears to copy the whole post.. Anyhow I'm going to try to keep it short (As you already know I'm not known for short..)..
Canned Air; I remember years ago when canned air was made with Freon the cans stated that (Dust-Off brand.) it was specially design for using on cameras ,,etc. Yet not that I read every can , I read a lot because I would love to if cans that don't say "Do not use on sensitive items like camera mirrors and coated lenses. Yes I was once told by a mechanic when I went to him with a caliper issue that the manual in big bold letters said "Do not use air .." well he used a few pounds of air, so I asked him "But the manual stated use no air,," he looked at me and said "I never read the manual I just know how to do it !!" On a job site I did see somebody cleaning an instrument with front coated mirrors, lenses and other fine optics with canned air , I asked him about the warning he stated that as long as you used it carefully and made sure you kept the can at right angle not to let any of the liquid come out it's fine. I know my limitations and spray cans are one of them, if you need something screwed up with a spray can send it to me , paint , lubes, glue, etc.
Bulb blowers , I never thought of using them in vacuum mode like one does with a de-soldering bulb.
There are ESD vacuum cleaners, but DIYers did it long time ago for computers:.
I have 2 service vacuums I believe one for them is ESD proof, yet I presently can not get to them, in lue of them I have a battery powered keyboard vacuum that just might fit the need..
With finest microfiber cloth such as for glasses it works perfect but they have to be cleaned as well.
I ordered the some of the highest rated from Amazon.. As I stated above I have a few really high end lab instrument lint free cloths yet they leave 1" or larger threads all over the place !!
Thanks everybody for all the fantastic tips.. I'm getting itchy to clean my cameras, yet I have to wait until my supplies come in.
Lens brush, yes / no ??

It is pretty straight forward but sucking air out is better than blowing air in.
For this you can use a vacuum-cleaner which can be set for low suction. You need some kind of extension for a smaller tube.
Now you have to built an antistatic protector which can easely be done with a single cable, one end is on the earth terminal of the mains plug, the other end stripped for about 5 cm.
The bare thin copper wires to inside the tube and remain there. You fix this cable with tape to the tube and now you have the possibility to suck air out without any danger of electrostatic problems.

There is nothing wrong in cleaning the mirror! Of course anything that can scratch it...
With finest microfiber cloth such as for glasses it works perfect but they have to be cleaned as well.
Canned air: Depends on which one, in Europe we have Ballistol which works very well.
Air Duster with 80 liter spray volume.
It is particular for sensitive electronic equipment and digital cameras.
But one has to work first a bit with it, get used to it, understand it.... and maybe waste some of it.... better than to produce hot air....
