To me 20 times in a year seems a bit excessive, are you sure it's just dust.
My D7000 had and was repaired for the lubrication spray issue, and even with that, I only felt compelled to wet clean the sensor two times in a one year period. And in the 3 years I used my D80 I never did a wet cleaning.
And it's now been about 2 months since I've gotten it back from repair and the sensor is still relatively debris free. Before the repair I would have had at least 10 significant sized spots reappear on the right side of the image after a wet cleaning.
Do you have any example images of the spots for us to analyze?
I believe the amount of times I've had to have it cleaned is excessive also. Many of those cleanings have been wet ones by the camera store staff. And in my case I keep getting the same spots in the same location in the right upper portion of my images.
I do have one recent image I can post here for review.
Thanks for the link. I read most of all the responses until I noticed the posting about the lubricant/mirror/motor issue. It appears to me that my spots like the ones you had are not small dust particles, but perhaps lubricant.
When you sent in yours for repair, did they replace the mirror motor and mirror mechanism?
Was it repaired under warranty for you? If not can you give me an idea of what the cost might be if mine is the same issue?
Jim, I had the same issues as Pete and mine was repaired under warranty. They did replace the shutter charging motor which was spraying lubricant spots onto the sensor. Mine was repaired in January ( about 1000 photos ago) and I've not needed to clean it at all since then. They also repaired/adjusted my autofocus which was either bad as a separate issue, or bad as a result of the lubricant spray collecting on the CAM autofocus unit.
We've seen reports of this flaw being repaired even on out-of-warranty units.
I think it would be best to get it to Nikon as soon as possible.
I hope the camera store has not been charging you for cleaning the sensor. 20 times is excessive and while you do have something on the sensor, that is completely unreasonable. Unless you have used the camera in an extreme environment, 1-2 cleanings would be normal. I have two D7000 cameras used for 15-20,000 images and they have never been in for sensor cleaning.
The store should have recognized that there is a problem if you are having your camera cleaned every 2-3 weeks. Stores do have the ability to help with service, so if Nikon denies a repair under warranty, the store may be able to help with a report on how many times they have cleaned the sensor.
Jim, mine was still in warranty, so I didn't have to plead my case. I was concerned they'd not admit to the "oil on sensor", but they did, immediately and took all the necessary actions to make sure it was fixed completely.
Eric has a good point below...that the store might be able to help you plead the case since they've cleaned it so many times.

Eric and Charles make a good point about having the local shop as a secondary validation source, but I’m not sure it is necessary but acknowledge it’s good to have.
I did my own cleanings, and provided no proof of those cleanings other than mentioning it in my letter. I didn’t even provide any sample images, although I mentioned in my letter that I had before and after images of those times that I could provide if needed.
It was either in my thread, or one of the other threads about this issue where it was suggested that if there was a spray issue, then there would be an accumulation all over the area that could easily be detected, not just on the sensor. I think Charles even made the case that it could potentially be spraying on the Phase Detection sensor which would eventually impact its performance. Something I never thought of when I thought it was an excess lubrication issue that would abate by itself over time.
So even though I plead my case that the issue occurred well within the warranty period, the tech was most likely able to see that spray accumulation and determine that it was indeed one of the units affected by the defective seal on the charge motor. And it also appears that Nikon is willing to do right by its customers in resolving this with cameras just out of warranty.
So send it in with an open mind and hope for the best possible outcome.
I just checked. I have > 27,000 shutter actuations. I have had to wet clean sensor twice. My dust was never near as prominant as yours and would imagine it is lubricant. Also consider cleaning sensor yourself. I use the cooperhill method and have never had a problem. You can search it on google.

I purchased my camera in December 2010 and have never cleaned sensor but have noticed several spots. I took my camera in for service at Nikon because of suspected back focus (????? I was reading to many blogs so got paranoid) and asked them to clean the sensor. I was told that spots are oil and early production units had this problem. Cleaning will not fix it so mirror assembly replacement is the only option. It will be done for free. Love my Nikon service centre. Camera is 4 months out of varanty. Found the spots when taking photo of white paper with 35mm lens at f/20. Did not effect picture taking but could be the cause of some of my focus difficulty.
After Nikon received my camera, I got a service order number, which I input online to check the status.
I was pleasantly surprised to see that repairs will be complimentary. The status report indicates a catagory of C or "major repair, major parts replaced. Not sure what exactly is being done. My status as of today is "in shop".
When I called Nikon Customer Service to check with them, I was told a major repair usually takes from 7-10 days, at which time the camera should be shipped back to me.
I'll update here again when I get notification of what was done.
Great to hear. I will be interested in seeing what you think of how your camera works now. With mine I have a sense that even though I thought my focus worked properly before the repair that it's even better now.
Branko, I'm happy to hear that Nikon is taking care of your camera. The oil spots probably did affect my autofocus (oil on the separator lens of the CAM4800). You will be delighted with the repairs, I'm sure.
