We have a small tripping to be made, not a lot required and it won’t take us very long I hope. One important item that I do require is a sensor cleaning kit for my camera. I have been meaning to get one for a ages.
At first I though and was told that the senor could be cleaned by an expert. (In this case it seems that an expert is – ex being an as been and xpert is a drip under pressure) sounds better that it looks).
It seems that all the camera manufacturers having been some economical with the truth, when cleaning the sensor you don’t actually touch the sensor it is covered by a piece of glass and that’s what needs cleaning. So according to article it is a easy but delicate operation.

I have to clean the sensor on my S2Pro regularly - it seems to be the best dust-magnet on the planet!

Just follow the instructions with the cleaning kit and you'll be fine. The real trick is two swipes of equal pressure, left to right, then right to left.
Incidentally, I get my cleaning kits online direct from Sensor Swabs.
