That's a fantastic idea, microetching the surface....
Dust is a problem for me too.

Strangely at first the MISPRO was great, i left it in the printer over
several weeks with the cleaning pump totally disabled and it would still
print without fault after weeks of standing still. This went on for a few
months with no problems, but now suddenly it is not printing on all
nozzles, and resists cleaning so far.
