discussion Clearing varnish through AB?

[pjgtech]

Another noobie AB question....
How do you know when you have suitably cleaned / flushed through the AB enough when using clear varnish?
Obviously with any sort of pigment/paint, you can see if any paint is left after cleaning/flushing, but not so with anything clear!
I assume its just a matter of making sure you give it a good clean and flush, and then hope for the best? Or is there something else I have not considered?
Cheers
