Is it harmful to use a sensor cleaning kit for Nikon on a Canon DSLR?

I would never touch my camera's sensor with anything, cleaning kit or not. You can easily ruin the camera. Your best bet is a professional for a cleaning.

If you buy a cleaning kit from Photographic Solutions, and explicitly follow the instructions, they guarantee you will not damage your sensor.

I've cleaned my sensors many times with this kit.

But this may not be appropriate for the faint-at-heart, or if you are not tech-savvy.

Yes!

In fact it can be harmful to Nikon dSLR's as well. For sensor cleaning activities, pay someone else to do it. The best would be those guys at the authorized Nikon service center.
