How to store molds?

The moulds I am currently using are on handles on the casting bench. The others go in a cabinet. No oil or anything like that. Most of my moulds are Al or brass so rust is t an issue.
Brad ain’t got time for fancy organization systems.

I'm sorry to hear of your health issues.

I store mine with mineral oil applied with an artist's brush. I've not had one set for longer than about a year though like that.

While it seems to be popular, I cannot picture oiling a clean mold. I store them in MTM dry boxes with desiccant and VCI paper.

At large, whereabouts unknown.
I use VCI paper as well, but in Plano multi-compartment plastic boxes, kind of like the ones popular for fishing lures, but much larger. I inspect them all regularly.
That said, I've bought a lot of used moulds that were allegedly put into storage in the '50s & '60s that were put up in grease. Sometimes the grease was dried and cracked, but every one I cleaned up had no signs of rust. Still, I try not to buy moulds packed in grease anymore.

I keep mine in a climate controlled shop. I live in Mississippi, it’s humid here here year round, I have had to resort to storing my irons coated with WD40 to keep them from starting to rust. Nothing pisses me off more than to go to all the trouble to clean and dr my molds up to have them start rusting. I just go ahead and spray them after they cool off now. Quick wash off with brake clean, and a soap bath and they are good to go. I’ve got to go through all mine and double check them and coat again soon. Long long term, I’ll probably submerge in oil. Its gotten to the point I’m at this crossroads, but going the WD 40 will work along with the climate controlled shop.

I also like the mineral oil idea I’m going to have to try that out.

i have molds that haven't been used in 35 years (probably should sell them) thay are wrapped in rust preventative paper (brown stuff). they are not treated with ANYTHING. then stored in a 50 cal ammo can. nothing shows any sign of ANY rust. don't make this a hard process.

I live in a very damp environment.
Now I use Kroil on my iron ones and store the Aluminum dry with a desiccant pack.

But I have heard people locally rave about using one of those food saver, vacuum storage systems. Then storing in an ammo can.

I really like this for long term in very adverse conditions.

I use my vac sealer for many, many things when I expect the worst conditions. Nothing like being able to pull out bone dry cloths for instance after taking a dunking in a river on a canoe hunting trip... spare Ammo sealed. Tinders... Let
Your imagination run. Its awesome!
 
Hard to keep rust at bay here in Houston but oiled, tightly wrapped in paper and stored in the house does a pretty good job for me.
