How to stop constant rust?

I am having an issue with a couple of my guns constantly getting little specs of rust on them.

I have an old model Marlin Model 60

and my brand new Kahr CW-9


everytime I put either of them away for more than a couple of days they get tiny traces on rust on them.

The Marlin on the outside of the barrel and tube.

The Kahr on the slide.

I guess my house is just damp?


What can I do to keep this from happening?

I clean the guns regularly and after I shoot them but it still happens.

I have tried keeping them in factory case, in my sock drawer, and several other places. Nothing changes.

I am also having trouble getting some of the spots off the Kahr. I let it sit with a good amount of oil on it and rubbed with a terry cloth for a good while and it didn't help much.


I feel horrible I have let this happen to my beautiful new pistol but I don't know what to do, or what I could have done different.


I have a Walther P22 with gun-metal slide and it has never had this problem and I have had it here in the house over a year, whereas the Marlin and Kahr are new.


Any tips would be greatly appreciated!!!


Thanks,

Don't store them in a case, or your sock drawer, the fabric/cushion material can collect moisture and make them rust, had a marlin 336 that someone stored in a case before I got it, and I spent a good hour with steel wool on it fixing the mistake. Steel wool will generally take the rust off without damaging the finish, but try it first, like in a small, out the way area of the gun that won't show, to make sure it won't hurt whatever finish you are working with. Before you put them up, or after you handle them, wipe them down any metal parts with an oily rag, then try to avoid touching the metal as much as you can, the natural oils on your hands can make a gun rust. If you still have problems...try a dehumidifier maybe? There's also some products on the market, and recipes for homemade versions of them that are designed to absorb moisture.

Get some of those little packets that says "Do Not Eat" on them out of beef jerky or some pill sample bottles. They are made to absorb moisture.

Make sure to use 0000 steel wool as the coarser variations will remove your finish in a hurry.

Careful cleaning and wiping with an oily cloth is an absolute must after every handling. Do not store in an enclosed storage without venting. Use Desiccant packets [available from your gunstore at about a dime each]. For handguns I recommend using VCI paper [like S&W uses in shipping]. VIS [Volatile (or Vapor phase) Corrosion Inhibator paper emits a small phase vapor displacing moisture and prohibiting the rust process. VCI paper is available in 1000, 16" square sheets for about $30 from U-line. You can also likely score some free sheets from a local manufacturing facility that makes and ships ferrous metal products.

Be sure to oil them lightly before putting them away. I generally put oil on a rag, wipe the gun, then use a different area of the rag to lightly wipe off the extra. This is my typical practice, and it has worked well for me. Good luck

Try a pencil eraser on the light rust to remove it .

Dunno about the old Marlin, but I've got a Kahr PM9 (stainless slide) and a Ruger SP101 stainless that sit in bookcase in office.

My crib sometimes uses heat/air, about 3-4 months out of the year in spring/fall just windows, like now. Anyway, no rust on either of these stainless babies in about a year and a half, pretty much same humidity here as there.

I wonder if it isn't something about that particular Kahr and wondering if maybe you should get in touch with their CS?

Even my Hi-Point hasn't rusted.

HA.. I just had my Marlin 60 completely refinished for the same exact problem. When I got the thing it had a little rust on it, I did everything from dehumidifiers, oil constantly, etc etc. still every few days, RUST. Finally I got tired of it, after a year of fighting it. Last week I gave it to my smith to re-blue, just got it back today. He said that there was microscopic pitting and he had to put it to the sander but it looks good. Once it starts its hard to stop it, unless you refinish it.

Thanks for all the responses guys.

I could probably be more careful about wiping it off after handling with a light oil rag.

I will look into some of those moisture sheets.
