I've been following this thread closely since I have a three and a half year old D700 that has never had the sensor cleaned. I watched the Copper Hill video and ordered a Universal kit since I also have a D200 that can use some attention. I picked up an Arctic Butterfly last week which did an excellent job of cleaning the dust from the D700 sensor, but there is evidence of lubricant on the sensor so I'll deal with that next.
My understanding is that Copper Hill's "Quick Strips" are cut from Pec Pads?? I researched Pec Pads on Photographic Solutions website and under "To learn more about Pec*Pads"...I came across the following warning, "Pec*Pads are NOT recommended for cleaning CCD sensors. Pec*Pads are not made from the same materials that are used in Sensor Swabs. Photographic Solutions does not approve or warranty the CCD or any camera part from any damage caused by using non approved products." Does anyone have any thoughts on this? It appears that Pec*Pads are being widely used for sensor cleaning yet contrary to the recommendations of the manufacturer.
