I would like to find a better way. I heard that some flap type disks
are better than wire brushes and are particularly good at this task.


I use surface conditioning flap-disks from my local engineering supply store.
Like Scotchbrite on crack-cocaine. They are coarse and open and fit on an
angle grinder. Goggles, mask and coveralls definitely required. Don't use the
conventional sandpaper type flap-disks. They load up and stop working.
