Specialist cleaner and swabs arrived today - took 4 more washes to shift the specks on the D850 - there may be a few tiny ones left around the edges but I am quitting while I am ahead!

Amazingly, the D810 that I did all the work on had very few dust bunnies - one wash got them gone.

I must say I was a bit concerned because these cameras have no low pass filter over the sensor, so you are working directly on the most sensitive part.....

I think you are wise to stop. You can chase your tail getting edges 100% clean when invariably most peopl crop the images to some extent.  

I wonder if the owner of the 810 was just more attentive than the 850 owner?

The sensor itself does have a protective glass surface which is the same resilient material as filter glass …so swabbing should be no less a concern…unless using a Brillo pad (or dry swab)

Possibly, the history of both bodies is unknown but the high shutter count of the 850 (740,000 ish) suggests maybe professional use.

I spent a lot of time blowing bits out of the 810 as I built up and shaped the missing plastic of the shutter box - maybe that helped clean dust off the sensor?

Anyway, super happy with both now and the 610 sold for good money this afternoon.


Remember to switch on the Clean Sensor at Power Down in the menus.
Yes, master :bowing:

If you follow some tips like ..... the Self Clean, Change Lenses with Body throat facing down, Don't change lenses in windy conditions, then the self clean seems to stop most dust.
Changing the lens with camera body throat down or definitely NOT facing upwards is a winner!

One thing that is not obvious is do not store camera on its back as any dust dislodged will then fall back onto shutter or sensor.


These days I find I seldom need to clean my camera(s) sensors.  This is possibly because I am not shooting every day but also because the newer sensors are not dust magnets like the older ones but also because of following the simple tips above.

Apart from the sensor self clean (now set) those are what I always do - my D90 and D610 never suffered from dusty sensors and I am hoping these two remain dust free.

I like a suggestion I saw elsewhere which is to put some double sided sticky tape inside the lens and body caps to catch any errant dust
