Household ammonia is very inexpensive Place the pan in a plastic
trash bag and pour about an ounce of household ammonia into the bag
and seal the top of the bag with a twist tie... do this outdoors, and
add nothing else, no soaps, never any bleach. The ammonia fumes will
dissolve the schmutz, not the liquid ammonia. Leave it outdoors for
maybe a week and then wash the pan with a sponge and dishwashing soap,
should clean good as new without any scrubbing.
