Nope, never did that (scared of making things even worse)

 

It's nothing magical, but one needs the right tools. Unless you don't pour in the liquid and work without haste, there's a very good success rate.

 

I have a statical brush, wet clean set (which I use as last possibility), the eyelead system (Pentax has something similar), a rocket blower and a loupe which fits the mount and is illuminating the sensor - otherwise I cannot detecct the particles.

 

Usually I first blow the sensor.

check with loupe - if good, stop here.

Use the static brush for particles which are happy to get kind of a load

check with loupe

use the eyelead stick to get the stickier particles

check with loupe

After that it's time for wet service.

 

The static (motorized, to charge the brush electrostatically) brush and the swabs are from visible dust. The liquid lasts very long, as I only need a drop or two on it. Swabs should be in sensor size.

 

I know a photog who does this kind of sensor cleaning in his bathroom after a shower. He thinks this reduces the dust. I'm not so sure about that (because of humidity), but I try to clean the sensor in place with less dust in the air.
