After watching this video clip I purchased several of these cleaning items and attacked my sensor. I am not sure but I think canon repair got lubricant on my sensor when they repaired my shutter. It was so bad I could see it without a loupe. It took two applications of the VisibleDust EZ swabs using both cleaning fluids and two applications with the DustAid Platinum DSLR Sensor Cleaner but it looks good now. Maybe my imagination but pictures seem less flat now.
Thanks for sharing the video clip.
