Mold release?

[pastera]

Other than 2-stroke oil on the pins and sprue plate bolt, my aluminum molds get cleaned with brake cleaner then heat cycled a few times in a toaster oven. No issues with sticking bullets.

Found the best use for the graphite spray release agents is the bottom of the sprue plate and the top of the mold. Give it a light spray on the sprue plate and then after stuffing cotton balls in the cavities a light hit on the top of the mold. Lubes the contact between them and eliminates lead sticking to the plate. A drop of synthetic 2 cycle oil applied with a Q-tip on the alignment pins and ready to go. On the Lee 6 cavity usually remove the sprue plate and apply a bit of hi-temp copper anti-sieze at the pivot point to prevent galling of the mold and plate. With the Lee don't forget to lube the pin and washer on the stop for the plate and a drop on the hinge of the sprue cutting lever.

I have used the Frankford Arsenal mold release spray. It is very hard to get out of a mold, what I have left I use to coat the end of the pins in a hollow point
mold. Those things can be stubborn but that mold release helps a bunch on that particular mold.

Once an aluminum mould is completely cleaned of all machining oils , heat cycled a few times and broken in with a few casting sessions ... it will become seasoned like a cast iron skillet and boolits will not stick .
If you have a cavity that is "sticky" spray the cavities with a Dry Lubricant that contains Teflon and let dry . The micro-Teflon particles form a thin film like a teflon coated pan and boolits want to jump out the mould when opened ... after a few uses you will no longer have to use it.
The dry Lube is the best "mould release" it doesn't build up and it doesn't make your mould black and cruddy and .... It Doesn't Contaminate the Cavities . Just try it once !
The stuff I've used in the past was Liquid Wrench Dry Lube L512 but I'm sure any brand will do .
If you need a mould release ...this is the best !

Teflon emits toxic fumes around 480°. The last thing I would put in a mold cavity would be something containing Teflon.

I basically do my own variation of all of the above. The scub is essential, I use a mild abrasive powdered cleanser called Bartenders Friend. I find that the Lee molds can have a substantial burr on the edge of the cavities, the scrubbing removes the burrs.

Sometimes I get a little too much two stroke oil on my mold. A quick spay with brake cleaner, followed by a clean q-tip swipe in the cavities, gets me back in business.
