Help me please. How to clean internal lenses of a zoom bino? Glass lenses (1 Viewer)

I need your opinions.
While I have a fair amount of experience cleaning binos, when I service zoom binos the inner lens should be free of any micro particles.
It takes a lot of work and requires a lot of patience to get them neat.
How do you do? Do you have experiences?

Owning a "zoom" binocular is bad enough, but trying to get it back into collimation adds another level of problems. So far, 100 observers have seen your post. However, most, out of imprudent courtesy, have remained silent. But if you read much in Birdforum or Cloudy Nights you will see: friends don't let friends use ZOOM binoculars. It is not a "feature." Please investigate that I not be the only dirtbag.
