Rust prevention for dies

[Pit4Brains]

My fairly new RCBS FL .25-06 dies are beginning to show signs of rust. Theres a tad bit on the top and some speckling around the brand / caliber stamp on the side. I looked at the resizing ball and it was spotted as well. I have kept my dies on top of my safe, in a closet, in an air-conditioned house, in Arizona. Our Monsoon just got going but it has been rather dry here, and the ac keeps the house fairly dry anyhow.
I disassembled the die and I have it drenched with G96 CLP in a tin can.
I know a lot of you are in the east and the south where the humidity is high..
What do you all do to keep your dies from rusting?

Here in PA it is humid but I've been lucky not to have a rust problem with my dies. That G96 should do a good job removing and preventing rust. Like with guns just leave a very thin film of G96 on the dies. A friend has rust problems with his dies and all he needed to stop the problem was to spray a little Remoil on the dies before putting them away.

Fine grit walnut media with some NuFinish does wonders on surface rust and leaves a nice residual coating that prevents future rusting (Since the media will pack inside the dies, you'll need to do some manual cleaning/polishing of inside the dies).

Rusty dies before:

And after some aggressive rust removal and polishing in walnut/NuFinish:

That walnut shake really did a job on those dies.
My dies aren't remotely as corroded as those.. have you checked the inner bore of those dies for pitting or any other corrosion damage?

These belonged to a friend and fortunately the inside of the dies were well oiled and had no rust. All the rusting was on the outside of the dies. I had doubts but the die surfaces polished up very well.

As to long-term rust prevention of NuFinish, these dies were polished in April 2011 and they are still shiny with no surface rusting!

Something like BDS's method....

Throw them in your vib tumbler with a good helping of bore cleaner.

Run it for a few hours.

Then throw it in your vib tumbler with Nu-Finish for a few hours.

I treat all the dies I pick up second hand this way, and periodically clean my collection as well.

It works amazingly...it really, really does.

Nufinish does a great job of preventing oxidization of many materials... tool steel being one of them.

I restore and clean socket sets and steel hand tools the same way..... bore cleaner is great stuff... I use hoppes elite.

Thanks for the tip BDS. Funny I never thought about doing it that way.

I use WD-40 for rust prevention on my dies. Works for me in the humid Florida summers.

One warning about putting them in the tumbler: make absolutely sure every single piece of media is out of the threads before reassembly. I had a 7.5x55 fl sizing die seize up beyond repair once when I tumbled it and put the decapping rod back in and a piece of media (crushed walnut hull) was still in the threads.

I have kept my dies on top of my safe, in a closet, in an air-conditioned house, in Arizona.

Depending on where the closet is in your house, it may not be as dry in there as the rest of the house. Generally, closets do not have air supplied to them and the air does not circulate in them.

Is Arizona so humid that dies rust in a climate controlled house?

My dies have been kept in my basement for 20 years with no rusting. With a dehumidifier, the humidity is usually under 50%....I wouldn't think the living quarters in an AC home would be higher.

I would think in Arizona your dies rusted where you handled them.I just wipe mine off with an oily rag before putting them away .I've never had any problems.Don't know about the expander ball

Break Free CLP is good for storage. Military uses it.

Then throw it in your vib tumbler with Nu-Finish for a few hours.

Is this done with the same media or do you have some that is use with the bore cleaner and some that is used with the new finish?

Definately some good ideas here.. Thanks

I know..

I like Eezox, but only because it's what I have for my guns.

No rusting yet.

I've tried a LOT of 'gun' oils. The very best light fishing reel and gun oil I've found in my 60+ years of toying with real guns (and reels) is any brand of Automatic Transmission Fluid; it has excellant lubing qualities, good penatration and very good film strenght that effectively prevents rust, all without leaving a film of gooey varnish when it evaporates as all oils eventually do. ATF not only works as well as any and better than most costly "gun" oils, it's quite inexpensive too; I get it by the quart from Walmart's automotive oil department.

Also generally, closets get slightly damp clothes put in them from the dryer every laundry day.

Actuall its the closet at the end of the hall. I't's my sporting goods locker with gun safe, ammo, compound bow, holsters, cases fishing poles, etc. I have hardwood floors and plenty of ventillation under the door. I don't think it's a humidity problem, but more along the lines of just being plain, exposed steel.

Put some VCI (Vapor-phase Corrosion Inhibitor) treated chips in the die boxes.

Replace about every year with a new chip.

I have never oiled my dies at all, some are nearly 30 years old and look as good as ones that are one year old.

The secret?

I have my reloading bench in my basement which is extremely dry all year 'round! Of course, in the most humid summer months (June, July & August), I run a dehumidifier as I also store many construction and woodworking tools down there which I do not want to rust, and which also have no rust at all. I do not have to coat or treat them with anything at all.

The other months of the year, my boiler with many zones and many, many feet of zone piping within the basement keeps the basement very dry.

I have never had a die rust either in 50 years.

Stored in the basement, which leaks through the cracked wall occasionally.

However I am blessed with nontoxic sweat.

I know folks who can rust the chrome off a trailer hitch ball just by touching it with sweaty hands.

Seems like you might be one of those, only just not quite as severe a case.

A good wipe down with a RIG-RAG, or even a wipe down and spritz of sizing lube should prevent it.

Moisture Barrier Bags for Rust Protection

Have you considered moisture barrier bags? Moisture barrier bags, (also known as foil bags, alufoil bags or mylar bags), are one of the most effective packaging solutions on the market today to protect against corrosive damage caused by humidity, moisture, oxygen, salt spray, aromas, grease and other airborne contaminants. Products bagged and sealed in properly controlled production environments will remain protected indefinitely, as long as the correct moisture barrier materials remain intact.

you can make your own little silica packs to throw in your die boxes. they sell silica in hobby shops and places like michael's. it'll be with the flowers and stuff because people use it for drying flowers. get some of those cone coffee filters and pour some of the silica in the there. trim it off and glue it closed. put one if every die box and replace it every so often. you can put them in ammo cans with your rainy day ammo too.

whenever you know you're not gonna use a set of dies for a while, put a good film of CLP on them, inside and out. you might want to wipe them off before use the next time, so put a note in the box to remind you.

Well I went and checked my .30-06 dies and whattaya know!

A big ol' fingerprint in rust..


I think I'll do the tumbler thing with the nu finish this evening and give em a little CLP.

I can get those at work for free. A lot of aircraft parts are shipped with them in the package.. Thanks for the tip!
