But I recently did up a couple of pieces for a show that specified Plexiglass in the frames - and was amazed that the nylon makeup brush actually scratched the dang plexi. The sensor cover should be harder than plexi (which seems to scratch with a just a hard look) but I'd still be cautious about running just any old brush over it.

Be as sceptical of that article as any other, for instance it says:
"Any nylon brush will accumulate a charge when blowing air through it: this is
a property of nylon. In other words, there is nothing magical about Sensor
Brushes in this respect."
If the nylon is treated with a very mildly conductive deposition process it can
become sufficiently conductive to drain any potential static charge.
