i was reading the canon site about how to take care of your lense. they mentioned using the canon fluid to clean the lense, but i'm sure there are other brands out there.

so what do you guys use for cleaning the lense? and do you use the same fluid & procedure to clean in the glass in the back of the lense as well?
