Ioan,
You can try media blasting.  If you go with chemical removal, any kind of 
solvent splash from a directed stream would attack the coating outside of 
your rework area.

Try a Crystal Mark Swamblaster and their wheat starch pellets, or CCRD 
with their coated plastic beads.  You will not have fibers anymore, but 
you should be able to blow most of the dust off and rinse the rest off 
with water.

Dear Technos,

We need to locally strip the acrylic coating (1B31S) from a few 
components, on a few thousands of boards. Right now we're using Q-tips to 
do the rubbing and, besides having to pluck tons of fibers afterwards, 
we're also going through a lot of Q-tips.

So the question is: is there anything else we can use, that will be more 
effective, cleaner and more economical?

Thank you,
