The problem would be damaging fine traces. Some nylon brushes have very
stiff bristles and would easily destroy photoresist. A toothbrush would
be too aggressive. A synthetic paint brush is good, but I think it
doesn't give even abrasion as a foam brush. I too often get spots where
the paint brush hadn't completely removed resist residue. The foam brush
seems to do a better job.
