I sure wish anyone that uses a spray release agent on a mold had to clean the mold themselves. I recently got a Lee 6 cav. in 45 caliber. The prior owner must have used some kind of chemical mold release every time he used the mold. I tried the mold one just the way it came to me. An it cast .003 under sized.
I have now spent an hour using a toothbrush and soap and have only taken off about 2/3 of the black gunk. And every inside corner still has traces of the stuff. At this time the mold halves are in a boiling pot of soap water hoping more gunk will come off.
If the boiling doesn't work I mite have to resort to spinning a bullet in each cavity to try to get more gunk out.
