Spray on oven cleaner removes it in seconds.

which is also a strongly-basic cleaner (mostly lye).

However, that won't get it out of nooks and crannies you can't reach with
the spray. It's great for open surfaces, though, and won't hurt
steel/iron. Eats hell out of Al, but then, so does TSP.

Oh, and another thing that melts away grime amazingly well is to spray it
with ether starting fluid.

This does work well, but do it outside, even if the weather is
unpleasant.

Ether fumes are extremely flammable, and if used in a basement, may
find their way to the pilot of the gas-fired hot water heater and
explode. Or be set off by the spark in a light switch or a control
relay.
