Removing rust from a rifle bore using Evapo-rust

[Tbag]

I have noticed some rust in the barrels of my rifles and I was wondering if I could use this rust remover I got from lee valley to remove it. The stuff is called evapo-rust, its non corrosive, non toxic and it works by the process of chelation. I used it to clean my rusted micrometer sight and my stripper clips when I first got them and it does work. Depending on how much rust there is, it takes from an hour to 24 hours to remove it, I'm just wondering if it would be safe to use on a rifle bore and if so how would I plug the barrel so I could let this stuff work away at it?

Any product that removes rust chemically that I'm familiar with will also remove blueing so I would be very careful with it.

Yep, very careful. should work fine. I use penetrating oil and a wire brush when I got rust. Nothing fancy.

Start with the least abrasive method first. I'd suggest liberally applying kroil to the bore with a patch, let sit for a few hours, and then aggressively scrub with a copper bore brush. Repeat a few times if necessary.

For future prevention I would also suggest investing in a good dehumidifier for the gun room.

Wax plug?

I have used Evapo-Rust on old motorcycle and tractor parts and it works well. I've never used it on a gun, though.

I think I should rather not try it. I'll try the least abrasive method stated by Bog Walker

What Bog Walker said! Evapo Rust will eat Blueing like a fat kid on a Cheeseburger! I seen those results, mot mine. I was asked " how can I fix this?"
