What is a good humidity range to store our collectables in that will help prevent rust? I have a dehumidifier and it has humidity range settings. I don't want to make it too dry either.

It's recommended that firearms be stored at 50% humidity and 70 degrees Fahrenheit.  Since steel molds rust - store them in the same environment

Thanks to all that have replied. The readout on the dehumidifier is running at 52 %. I must be in the ball park and I will keep it there. My molds are stored with a spray of WD-40 and then wrapped in several layers of plastic bag. It seems to be working well. Also I been wiping down my firearms with a cloth that has Break Free CLP. So far so good.

Same here in Nevada- sometimes our humidity is as low as five percent. Seldom over forty. Except when it's raining- both times a decade. Rust is something you bring from the coast.

I'm starting to worry now, and never have previously in over 45 years of reloading, and owning firearms! I've never done anything to my molds, guns, or safe storage before. I have my guns out often, and wipe them off when they go back in the safes. I toss my molds in an old milk crate, and get them out to cast again later.
Now I'm thinking I must be doing something wrong? Unknown what my humidity is, but all my guns and molds are in our finished basement, so never too hot or too cold. Guess I need to get a meter and figure out if I just got lucky on humidity, or my stuff is all going bad and I don't see it yet?

Same here Mike in Modesto Ca. my safe is in the unconditioned garage and not a problem.

Dave, Here in upstate New York we get humidity in the summer months. We have to keep our molds oiled to prevent rust unless they are stored where the humidity is controlled. I spray mine with WD-40 and wrap it up in a plastic bag. When it is time to cast I clean off the WD-40 with carb cleaner and then per-heating at the edge of the lead pot they cast good bullets on the second or third pour.

Marlinguy, After I clean my mold with the carb cleaner, I dry it with cotton cloth and Q-tips. The mold is then set atop the lead furnace to heat as the alloy comes up to temperature. 
Thanks for the info.

Phosgene does not kill instantly but rather slowly and reliably. 
LC100 is >5330 mg x min/cu m
for reference sarin (GB) is 35 mg x min/cu m
Phosgene in simple terms irritates the lungs and you drown. 
At low concentrations onset of symptoms may take 4-24 hours. 
Odor is like newly cut hay. 

Cheap and easy humdity:
add water to glass with a little ice. 
stir and wait for condensation on glass
record temp of water/ice mixture as well as ambient temp. 
google dewpoint, use table to obtain relative humidity. 

Yes, I know ... TMI

use to use brake cleaner on my molds. for like 10 years had ruff looking bullets and thru more back in pot than I used. and my good bullet were not that good. found out I had to clean my molds in hot soapy water to get them casting again. We are talking mostly Lyman molds. Its like it ( brake cleaner)gasses off and makes small pocks on bullet.. pocks is that a word? anyway bad bullet fill out

Don't EVER keep things wrapped for long in plastic; it's air-tight and since things therein can't breathe (hence the warnings on plastic bags) any moisture plus oxygen already therein can't get out.

Have had RemOil turn to sticky goo over time, so I quit using it.
