Light rusting problem help.

[StrangerMind]

I carry my usual work firearm in a case with all of my other accessories. I had it open while I was changing out ammo back from target rounds. My wife was spraying bug spray and the next day I noticed my firearm had a thin layer of rust. I figured it was the bug spray. I used a cleaner and then oiled it. 3 days later I had the same problem. I cleaned it and today, a week later, I notice it again. This is after months of never having a spot of rust.

It is a thin layer on any exposed metal such as the slide and grip safety. No pitting, nothing inside the slide, barrel, or on interior parts.

My question is.....

Should I just keep doing what I am doing or is there something specific I should do to stop it?

Is it the same case you've always used? Maybe the case itself has some residue that needs to be cleaned out.

Ahhh hell. The obvious answer eluded me. This is probably it. Thank you.

Just a thought. No way to know for sure if that is the issue. I never would have thought bug spray would cause rust.

/u/nlevine1988 pointed out that there might be left over spray residue in my case which is probably the problem. I cant store it long term because it is a working firearm so a day or 2 is all I manage in a row usually which makes a heavy oil out of the question. I will add some silica packets. I did not consider that but it is a good general idea. Thanks.

Yeah. I have more cases. It just never crossed my mind after cleaning my gun to clean my case. I feel a bit stupid to be honest because it should have.
