Before I started... dust everywhere



First try with the Visible Dust 1.0X brush.. it seems to have pushed the dust aside rather than lifted it



Second pass with the VD brush, this time it has picked up more dust but has left streaks.



Another try, leaves more streaks/scratching. I noticed a black glob on the brush after this.



Wet clean with alcohol based cleaner fluid removes dust and fine streaks, but leaves its own set of huge streaks (see right of image)



A tiny amount of distilled water finally gets rid of the streaks, and most of the dust. Am I game to drag a dry brush across it again...?
