How about sandblasting the offending remnants?

That would probably damage the "textured" plastic finish. Sandblasting
soft materials, like plastic, causes the sand to imbed itself into the
material. I learned this the hard way when I tried to sandblast a
brass welding torch. The sand is now a permanent part of the handle.

There are moderately inexpensive kits for craft/hobby glass etching that
used "canned air" and also the only slightly more expensive Paasche "air
eraser" kit.

Well, I have a Paasche air brush. Looks exactly like mine, except it
has a sand bin attached. I really don't want to run sand or glass
beads through the tiny nozzle. It also seems like it would take
several hours to do the job and probably won't remove the rubber goo.
My guess(tm) is that it will simply mix some sand into the rubber
surface goo, without actually removing anything.

It's not going to be fast (the active spot is roughly 0804-sized) and if
the plastic has already been softened by solvents you might just end up
with dirtier plastic.

Yep.
