Rust on DIES

[Swedonia]

Will try the vinegar on some surface-rusted Hornady pistol dies that were recently given to me. Does it matter if it is cider vs white vinegar?

White vinegar is what you need.

Clean off the rust. Use anti-corrosion spray (it will neutralize the corrosion cells). DON'T COAT WITH OIL. Use wax instead. Suggested waxes: MinWax furniture wax or Renaissance Wax (used by museums). When water (from humidity) gets on oil, the oil floats away from the surface. Waxes are higher molecular weight and don't float off.

You can also get some ZeRust bricks from Amazon and put one in the cabinet or drawer where you store dies. It puts out a vapor that kills corrosion cells. (Corrosion is an electrochemical process, just like a battery. As long as a cell is in place, it will corrode. ZeRust and other anti-corrosion materials are attracted to the cells and then block air from it, effectively killing it.)

I don't like using vinegar to remove rust as it tends to cause flash rusting while you're drying the parts off. I like to use phosphoric acid. Not only does it dissolve the rust, but it leaves a thin coating of iron phosphate on the surface which inhibits corrosion.

You can get it at Home Depot or Walmart as Metal Prep for about $18/gal, or as Milkstone Remover from a farm supply store.

So far, one of the best products I’ve found for removing rust & old bluing is
Metal Rescue.

You can find it at Auto Zone.

So I have some dies that were rusted up that I got from my brother in law - RCBS 6.5x55's - that were pretty dingy.

Soaked 'em down with some evapo-rust for about 2 days (I was lazy) and they look pretty good.

If you really want to waste some time search corrosion test gun oil and head down the rabbit hole. I’m not sure if salt spray testing is really a valid measure of how well something works in normal conditions but I had eezox and that’s what I put on my dies when they had to get moved to the garage.

I had some Eezox years ago. Odd smell -- not bad, just odd.

Soak in vinegar, use an old tooth brush or a small brass parts brush for stubborn spots, rise with water, blow dry with a gun and then lube. GTO.

Hello all,

I was going over some load notes and notice some rust starting to form on some of my gages / dies and my Forster press I bought a couple months back.

What the heck is going on. Before it gets worse is there a certain spray I can use to keep the rust off and keep them lub at the same time.

Any feedback would be awesome...

Thanks,

Just make a habit of wiping down every thing you touch, when relaoding, regardless of
the weather outside. Yep silicone is good thing, have some industrial grade machinist
oil from shop i use, mixture of different lubes, never had a problem with it.

I've had good luck with Birchwood Casey Barricade. Seems to have good rust prevention. I thought this guy had a video on it but he tests other alternatives. He tests all kinds of stuff in all kinds of ways. Even has one on rust converters.
