Here's cannon's official method

Seems scary, but also looks very effective.

I have a Canon 60D. I have a lot of dust on the focusing screen - how hard is it to clean that - and how would you suggest I do it?

Also, my rubber grip is coming loose. It doesn't really bother me a whole lot (on the bright side, it fits my hands almost perfectly!), but if I wanted to fix that, how hard is it to do?

Thanks in advance!
