The lens pen which will probably work best is the SensorKlear, it has a triangular brush head, so it would fit more easily/more readily into the tiny little aperture of the Executive series. I've used mine on my Fusion, and it works really well. I have one of the other lenspens, the minipro, and it doesn't work nearly as well unless you, I dunno, mangle the hell out of the brush in an attempt to get it into the aperture.
Hey people the best way is to keep it clean instead of cleaning it.
And another lesson I learned is DO NOT LOOK AT YOUR DOT CAREFULLY AND DO NOT INSPECT OFTEN
Trust me that's is the best way to stay happy
Just have fun with it otherwise you can even see scatter of the new one
well the camera doesnt pick it up as well, that stray is WAY BIGGER. It has gotten bigger from last time i think, not sure. All i kno is on the picture it shows up as a small stray, its much bigger. :-[
