ME WANT!

Note that what it is cleaning off is all black -- maximum
absorption of the energy from the laser. I used to test a NdYAG pulsed
laser (near IR -- 1.06 uM IIRC) by blowing printed text off boxes and
labels. It would do nothing to the white areas, but would blast off the
black ink, leaving a slightly roughened area. And you *needed*
protective goggles whenever that beastie was fired up. Even more so with
the cleaning shown, as it cleaned to a shiny reflective surface. :-)

Enjoy,
DoN.
