The self cleaning oven would probably do a good job on the belt residue
but would almost certainly result in damage to the aluminum's material
properties. The self cleaning oven temperature is around 500C. A quick
online search seems to indicate 6000 series aluminum experiences
recrystalization somewhere in the 250C to 300C range, and the effect
becomes pronounced around 400C.

A pulley might have sufficient design margins to tolerate the exposure
to high temperature without subsequent failure, although if there's a
key slot it may fail. I wouldn't heat 6xxx aluminum to 500C in anything
close to a critical application where I needed the original mechanical
properties.
I'd probably go with a version of the previous suggestion. Have the
bandsaw motor spin the pulley and use something like an ice pick to
mechanically remove the rubbery goo. I wouldn't push the tool against
the rotation in the manner of a wood lathe. That seems like a good way
to catch the tool in the workpiece, have it spun around and jabbed into
your arm. I'd let the tool dragging on the workpiece so it wouldn't
gouge and kick back. The material removal rate would be slower but it
should be a lot faster than removing the pulley, using solvent, baking,
etc. and then reinstalling it.
Good luck!

My bet is the toaster ain't going to work. What will work is if you have
a self-cleaning oven. But the pulley and any completely blacken cookware
you might want to also clean in the oven and run a self cleaning cycle.
Any organic matter will turn to grey ash and fall off.

So as not to stink up the house, would a $20 toaster oven do? It goes up
to about 425F. It would stink up the garage instead that way.
But not till warmer weather as the saw is in an almost unheated shed and
it will take a bit of time as the lower drive wheel will need to come
off to gain good access to the motor pulley. The shed is not well
insulated, so I keep the heat set to just above the dew point to
discourage rust on the machinery in the winter. We're on the inside edge
of the current four-easter, and its a bit chilly out, and still snowing.
Thanks.

Greetings all;
I have a Rikon 10-325 bandsaw. Trying to cut a block of alu with a
blade thats had one side of it dulled, the blade turned and bound in
the cut, and burned the drive belt, a 240J into the motor pulley.
Rather thoroughly welding the kevlar backing into the pulley.
Does anyone have a recipe for some panther piss that will clean it
out, or am I stuck buying another pulley from Rikon's parts dept?
Thanks.
