Hello
I clean carefully and cautiously the PO sensor with liquid, cloth and blower.
After cleaning sensor of PO digiback I see that dust jumps from air to sensor.
I see it under light and with magnifying glass.
I think the jumping will generate from electrostatic charge of digiback.
I’m right?
If so in which way do you minimize or delete electrostatic charge?

I think record shops sell antistatic cloth.
Luckily I think the sensor in a back is protected in a compartment, you are actually talking about dust on the cover glass. If the glass had a conductive layer on it, then earthing the whole case should neutralize the charge, and its actual origin is from ... your body, scuffing charge from the carpet
Which is why it's lucky the sensor is in a Faraday cage.
So you should be doing your cleaning on an earthed conductive mat. You can improvise one by using conductive foam - eg. PO packaging material - and wiring it to earth ...
