Dust Aid Kit
 

This might help others from making the same mistake:

I bought the Dust Aid Platinum (wet and dry) kit for my D3.

What is not made clear is that the fluid that comes with it should not be used on the D3 type sensors, as it causes streaking which you will not be able to remove - unless you use Eclipse E2 as I did.

Eclipse E2 is formulated specifically for D3 type sensors and I now have a spotlessly clean camera. Bit annoyed at Dust Aid though, had I not had my backup camera I would have been in trouble due to the time my D3 was out of action.

It's not just the D3 that requires E2 Derek. See this list:

for a full run down of which fluid to use with which camera.

Thanks for the info guys, I don't need the stuff yet but no doubt the time will come.

I understand this is because of a coating applied to the sensor anti-alias filter. This coating is charged one way or the other to detract dust and reduce its build up.

I must take approx 8,000 pictures per year and I need to clean it only once in that time. 95% od my shots show sky so dust is very noticable when present.

In this instance the camera was dirty from new (I suspect it was a spot of grease on the filter), but I photoshopped it out initially. However I do change lenses very often (and while I try to be careful, sports is not the easiest subject for me to be taking my time over) and I would say I easily take 30,000 images a year (in just one event I can take 2,000+) so now I'm happy to clean it myself I do see it as a good investment.

Thank you for warning on using E2 Duncan. Can you comment on the prelim dry stage of using the Dust Aid Derek?

I don't think I have ever got my D80 clean (using mostly Delkin non-alcohol on prepared & sealed wands); a bit inured to using 'Dust-off' function and/or heal. But I know I ask for trouble bringing out every possible nuance of grey in my skies.

Hi there, diving back for a bit while waiting for solicitors to start work on move, I am using a Delkin Sensor scope and the Arctic Butterfly for cleaning - I find it works on even stubborn dust.
