Very dirty Sensor

My sensor is very dirty, they are black spots and dust particles all over it, which shows up really well on pics with a lot of open space (skies etc.). I can't afford to take it to a shop to be cleaned, so does anyone know of a good sensor cleaning kit you can buy?

Thanks.

There's some great info in this thread Sally:

Also quite a few others (click on the search button to find them) :0

Sally it's just worth pointing out that the kits are expensive, involve some risk damaging the sensor, also they do not always shift stuck on bits. So you *may* have to have a professional clean anyway. We have some cameras at work that just have to go back to Nikon or an approved service dept sometimes. Wouldn't want you to find buying a kit and doing it yourself an expensive mistake by trying to save a few pounds.

Fixation UK will clean a sensor on a Nikon for £32.20 while you wait. I think you can post it too.

Judging by some of your photos I've seen - I would have it professionally cleaned, and then maintain it yourself thereafter.

If you want to sell your images I think this is the minimum investment you should make.
