Are you talking about regular cleaning or when you're actually putting it on?
I noticed that after applying it I have reduced the smudge factor by 50%, if not more.
For those of you who have yet to apply it, don't use a terry cloth towel as it just creates this tiny little hairs that stick to the back of the film. I wasted my first film doing that since they don't come off.
I bought some of these today. They are great for the screen, but they hold smudges way more than the screen by itself. I have just been using a microfiber cloth I use to clean my LCD's with.
If you accidentally touch the "sticky" inside part of the protector screen (which gets a perfect very visible finger print) you can just use water and a lint-free cloth such as a pec-pad used for cleaning digital camera sensors. Worked great. Still very sticky when dried off.
