How to clean inside gauge glass?

I'd like to try and clean the inside glasssurface of both my gauges, as you can see they are dirty in there from dust and condesation. The west is dusty at times. Can this be done? has any one done this and could give some tips? I tried serching and came up dry.

Also, any quick tips on how to post multiple pictures in the same posting? Thanks, I guess I'm computertarded.

Psssst!
You forgot to check the KZr archived site: Gauge Clean Up How To (by Wired George) :whistle:

The easiest way to post multiple pics in a post is to get a (FREE!) Photobucket.com account, post the pics there, then just place the image (IMG) links to them in your post and you're all set!

So you'll know how the pros do it, here's the link provided by Z1E:

Might want to give the search box a try. Seem to recall some former threads on this subject.

Thanks Retro and Patton. Wiredgeorge has it down! And the pros really make 'em look new. I'll try the photobucket account. Awesome.

neither site was really clear on restoring faceplate..
(unless i missed it ). just how is this accomplished?
