I’m coming in late to this, but…

…consider this stuff:

i had some frypans and saucepans that had that brown-black build-up on them, on their outsides, and i was not looking forward to a long session with the steel wool.

But, i got some of this (about $5.50 at Coles), sprayed it on, let it sit 15 mins, and literally wiped all of the muck away with a damp cloth.

Found that it’s also fabulous for cleaning BBQs, and the white enamel cooktop, that brown colouration that accumulates around the burners.

You do need GOOD VENTILATION, because a whiff of the fumes is quite scary.

While it may not do the whole job, i reckon it’d put a hell of a dent in the muck.
