I have 4 brass molds and all i did was clean them well and heat cycle them. Once at temp they drop boolits nicely. If you overheat them the boolits will tend to stick in the mold.

No, I just clean them (toothbrush and Dawn), heat them up in the mold oven to dry and get to temp, and start casting. They will patina themselves in time. I have well over a hundred brass molds (mostly HP's) and never had to heat-cycle any, and I have never used smoke or release on my molds. Get them to the right temp and the boolits will fall.
I just heat cycle 3-4 times and it puts some oxidation / patina on the mold...so far so good.
