Dirty Prism (Canon Elan 7)

[(Ghastly) Krueger]

Hi all

During the weekend I was taking some pics with my Canon Elan 7 in a very dusty evironment. Every now and then I gave the lens a blow (with a blower, not my mouth!) and brush to keep it clean, but after a while I saw some spots in the viewfinder.

The front of the lens was clean so I took it off, cleaned the back and the mirror but the offensive particles could still be seen.

Thing is, my prism is what is really dirty and I don't know how to clean it... I tried the blowing brush but the specs were too firmly attached.

Should I try harder with the brush?
Should I use some lens cleaning solution?
Lens cleaning paper?
????

Thanks!

I've got the same camera and the same problem. Solutions anyone??? I'm thinking about bringing my camera in to get a professional cleaning but we're in season here and I don't want to part with it just yet.
