1. Oven cleaner -- especially if this is mainly the inside of the
toaster oven door.

2. Powdered cleanser (or baking soda might do) takes a bit of
elbow grease, but can get most stains off of most glass or ceramic
things. (These may cloud the glass a tiny bit by its grinding action,
so I wouldn't suggest it for house windows without checking beforehand,
but it should be fine for appliance door windows which aren't expected
to be crystal clear.)

3. Scrubbing Bubbles or similar bathroom cleaner works wonders on
tobacco smoke stains; it might work here, too. It's also nice because
it's generally compatible with most plastics, where other solvents and
such are often not usable.


Good suggestions. I'd been thinking of Soft Scrub, because the calcium
carbonate (chalk) in it doesn't scratch. I'll try #1 and #3 if it doesn't
work.
