Rust issues.....

[Dr. Pepper]

Alright, I am an idiot and I'll come out and say it. I cleaned my Garand, and left WD-40 in the barrel. I didn't flush it out properly and I was greeted by a fine layer of rust in the forward section of my barrel. I applied a healthy layer of oil to prevent spreading, but I would like to know what is the best method of removal.
I tried to use a nylon brush and I found that to be unsuccessful, but I haven't tried brass. I also considered using CLR; however,I am reluctant to use because it can take off blueing and parkerization. If anyone has any suggestions, I would be happy to here them.

thanks,

Lee

I've had the same problem in my Mosin, all I did was soak it with CLP or rem oil for a few hours/days, then clean it as usual. Whatever was left got blasted out the next range session.

[Dr. Pepper]

CLP huh? I will have to try that; maybe combined with the brass brush I can get some results.

I would go with Kroil liberally applies to barrel and let it sit. Then patch it clean, bronze brush with cleaning solvent of choice followed by more Kroil as needed.

(substitute preferred quality penetrating oil of choice instead of Kroil)

My only question: does kroil remove parkerization?

I was actually just going to say this.

As the previous poster any oil you like will work, I've used both rem oil and CLP.

Kroil will not remove finish

Kroil will not remove finish

I use only Kroil for bore cleaning

[Dr. Pepper]

So kroil is specially formulated to break down rust, or is it just a nice oil to use for cleaning?

Kroil is a great penetrating oil that is great for bore cleaning and to use when you use a wire brush on rust....

Kroil is a low viscosity penetrating oil. Because it is so thin it gets within tiny spaces under rust and breaks the rust off the steel from underneath. It also has mineral spirits and naptha in it to aid in cleaning. It is not an oil in the traditional sense, it is a very short lived product that does not provide long term protection.

So it is a cleaning compound and pentrating oil. Think of what most people use WD-40 for, Kroil is better at doing it.

I buy it from MidwayUSA

Kroil, no doubt about it.

[Flintlock Tom]

I thought WD-40 was supposed to prevent rust!?

What happened?

[rojocorsa]

It says there he left it in too long thus actually promoting rust. Go figure.
