Got RUST? It's easy to remove, here's how.

I had zero luck with naval jelly. Poured it into my carcano bore and it appeared to accomplish nothing, even after leaving in for half a day.

I think you'd have to do some scrubbing.

Can't explain that one.

I did scrub it. I plugged the barrel, poured it in, ran a brush up and down to make sure it was filling without air pockets, left it sit for a couple of hours and brushed it out. Didn't seem to do much so I did it again and left it in there for half the day. No improvement and the color of the jelly never changed. Maybe it's the brand: Loctite Naval Jelly. It did not instantly remove bluing either. In fact it didn't do much to that either in the time I was running the brush. I was very disappointed.

Maybe find another brand of naval jelly...?

Was that Carcano made by FIAT?????

LOL

No. I suspect it's the brand. I put some on a bayonet to clean up the blade and it didn't do much to it either. Paid $9 for this stuff so I'm not real happy.

It's Loctite Naval Jelly Rust Dissolver. Only ingredient I can find is phosphoric acid. Says to not use it on chrome, aluminum, stainless steel or painted surfaces. What will it do to chrome? Remove it? I have some chrome I'd like to get rid of. But since it doesn't dissolve rust, I doubt it will do that either.

It would dull the finish of chrome. Make it a flat silver.

I know it works on a 870 barrel with a matte finish. Maybe not so good on polished steel? I feel a highly non scientific study coming on for this rainy weekend. Where's my lab coat!!!...results to follow....

Ok, this is the handle from my Rockchucker it has a nice blue job over polished steel.
The Naval jelly was used on the top half, Birchwood Casey on the bottom the tape separates the two.
The metal was degreased with Acetone and the jelly applied first.... Ah, screw it!! It worked just fine. Can't explain why it didn't work for you Aragorn.
