I just think you need to be more courageous with the cleaning fluid and do it several times. It’s been much exposed to contamination over recent weeks I guess. A full size swap would work on a final one sweep clean, but any size swab with fluid should be capable of more local attention.

I have looked carefully with a loupe at the sensor - I can't see any particles to lift with a gummy stick! If the camera is as well used as the shutter count suggests then I guess it is not surprising the sensor is dirty

I only use the fluid and swabs and never had an issue with them. May take two or three goes when the sensor is badly affected with spots.

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.....

Well done Chris. Persistence pays. Remember to switch on the Clean Sensor at Power Down in the menus.
