I bought an HP LaserJet 2300dtn on eBay for much less than usual
price. I soon discovered why it was so cheap. A past owner had
embalmed the printer in layers of bumper stickers, pogs, labels, and
rubber cement. Most of this was removed by the vendor, but I think he
just gave up trying to clean up the printer. Much of the glue and goo
is still attached to the printer, along with some dirt which helps
make the goo more visible.

I've tried alcohol, paint thinner, Goo Gone sticker lifter (citrus
power), Oops! remover, WD-40, ammonia cleaner, and 409. All of these
soften the gum and goo to various degrees, but leave enough imbedded
in the textured plastic surface to make the printer look filthy. I
hesitate to try a stronger chlorinated hydrocarbon solvent for fear of
destroying the ABS plastic.

Can anyone recommend a favorite solvent or cleaner for sticky goo and
gum?

How about sandblasting the offending remnants?

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.

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.

Looks like Harbor Freight has a knock-off (surprise!). Video over at
