if your trying for pure casting alloy aluminum, your probably going to have to buy it in ingot from a supplier.

Any oil or grease will burn off and add fuel to the fire. really dirty bits and pieces take em to the car wash and give em a hose down, or use a pressure washer if you have one.

Busting castings up in a wood splitter, its a good idea to throw an old carpet over the thing before applying pressure to stop any stray bits from entering the body.

funny how even the fun things in life have a bad side to them.

Yeah I was starting to wonder if I was over-thinking it, maybe just chuck em in and scoop the crap off the top of the pot. I have an old auto transmission that is covered in thick, oily filth and I have not been looking forward to cleaning it prior to melting, maybe I'll just not be too fussy.
