Reflector pans are those things that go underneath the burner on an electric stove. They're easy to remove for cleaning; just lift the element itself up and pull it out, and then just pick up the reflector.
Trouble is, they're not so easy to clean. In general, they are
only available in two types: steel or teflon-coated. The steel
ones rust and start looking awful very quickly. Cleaning does no
good, because it's the metal itself that looks awful. This is
probably what led to the introduction of the teflon-coated reflectors,
but there's a fundamental problem there: they don't reflect. The
purpose of the reflector in the first place is to reflect the infrared
radiation off the bottom of the element back up onto the bottom of the
pan. The teflon-coated reflectors are black, and therefore don't
reflect well at all.
Some people wrap their reflectors in aluminum foil. Perhaps
not a bad idea; it doesn't look very nice and it'll need redoing every
now and then, but it should work OK. But wouldn't it be easier if
you didn't have to?
This should be a slam dunk. Stove reflectors should be made of
stainless steel. Stainless steel is the ideal material for
kitchen use in general; no matter how dirty it gets, you can get it
clean and pretty -- by scrubbing it with steel wool or sandpaper if
There are dozens of companies making stainless steel kitchen sinks
that go in the counter just a couple of feet over. Any one of
these companies should be able to use the same tooling and materials to
just start stamping out stainless steel stove reflector pans.
There are also dozens of companies making stainless steel pots and pans
for use on top of the stove; any one of them should be able to produce stainless steel stove reflector pans.
