Cleaning mold before casting

[aap2]

I spray mine with whatever oil I have, rubber and the handles closed and store in a big 20mm ammo box. Before use I spray them with brake cleaner and compressed air (outside with eye protection) preheat and cast away. Works for iron,brass and aluminum and even in the salt air of Hawaii for 4 years.

I just wipe mine clean with a shop cloth and store. The iron molds I do put a light spray of silicone on.. and wipe dry..

I would NEVER spray any silicone-based product on a mould. A friend sprayed some on a 45-70 mould I loaned him and I like to never got it off! Too many good preservatives to fight with wrinkled bullets!

You must have put it on way way heavy and dripping. I'm talking gun and reel silicone, spray cloth and wipe. Have yet to get a wrinkle on that Lyman iron mold.

Coat with Kroil and keep in an air conditioned/heated room. No rust except for when I left them in the garage over a humid summer and got some spots of light rust on outside of blocks, but none in the cavities that I had wiped thoroughly with a Kroil-soaked Q-tip. If I had used a heavier oil they may not have rusted in the garage, but no real damage done. That's the only time I've stored molds in a non climate controlled room-I got careless after a move.

Degrease with generous amounts of denatured alcohol; it's cheap enough to drizzle some over the mold before detailed degreasing of cavity nooks and crannies with a Q-tip. I'm sure most of us have solvents like acetone or mineral spirits on hand that would probably work equally well.

Plano plastic boxes work super!

What's the product number or specific name of the Plano's?

New to casting but read every post I can.
Maybe to store your molds pollygunbag the bags off gas a type lube.

I spray my molds with Eezox when they are stored in the box. When I take the mold from the box, it is not cleaned with anything else except the pins are dabbed with paraffin when the blocks are heated up

When I'm done casting, I let the moulds cool completely, wipe down then spray with RemOil. Not the best oil in the world but I store my moulds in a 20mm Ammo Can. When ready to reuse, brake cleaner gets it all off quickly, dries with no film, and your ready to go again. Just my two cents

I clean my cool moulds after use and give them a coat , spray or Q-tip application , with Liquid Wrench Dry Lube . Next casting session just heat mould and cast...no need for cleaning, it doesn't contaminate and the stuff makes boolits jump out of the cavities. No rust and I reside in hot, humid , wet South Louisiana! Just try it !

Alcohol, propane, heptane, xylene, naptha, aluminum oxide..

That's pretty much liq wrench dry lube.

After flash off.. You pretty much have aluminum oxide left...

Well now... that sounds interesting.

My other hobby is salt water aquarium keeping. Makes for two very competitive hobbies.
