I have discovered wetting the workpiece with water greatly speeds power wire brush rust removal.  If you are using air tools, this is without hazard.



I believe the water softens the rust.  Plus it keeps the dust down.  Also prevents overheating the work.

Interesting!

I use water when sanding to create a slurry which makes for great sanding.
