Ideas On Removing Rust ????

#1

Post by Stevie Ray »

Any thoughts on what does a really nice nondestructive job of removing rust / corrosion from an older knife?

I usually use Flitz and a super fine Scotch Brite pad. Sometimes you'll have permanent staining, and there's very little you can do about that short of sanding it out.

Pencil lead works.It is best on guns,will take off the rust and not scratch the blueing.

As pencil leads are graphite they should work. You can also use the graphite powder. For heavy rusting a bit of molassis left on the rust spot for 24 hours will also work.

In hindsight the best cure for rust is defence. I use a product called "Lanox" which is a lanolin based spray - stops corrosion especially in the tight fitting hard to get to spots.

Thanks guys ... I've got a Wenoka dive knife (with the removable blade) that has rust around the handle. I'm going to try to take it apart this weekend. Prior to seeing this, I doused it with Liquid Wrench and let it soak for 24 hours.

I'm thinking I'll need to use something that will penetrate into the handle and get down to the screw. If the Liquid Wrench doesn't work, I'll try the Kero .... I'll post back and let you guys know how this comes out. Thanks for the help.

I had two Wenoka dive knives - one of them you could dive with in saltwater day in, day out, and it's still as shiny as the day it was made... the other would rust if you even looked at it funny. Who knows...

Hi guys

Since this topic is open. my Casco expanable baton is rusting badly for some reason, I thought these where made from aircraft aluminum?
Ive cleaned it off constantly throughout the handle and the expandable rods but soon enough rust develops inside the handle which looks like it has some kind of black powder coating on.

Anyone experienced this or have any advice to stop this?

The rust seems to jump on the metal rods from the inside of the handle but wipes off cleanly, I dont know if mabey the black coating inside the handle coulad contain iron and is infact the cause of this.

Cheers

The problem is two-fold:
-Remove the rust.
-Remove the obvious damage caused by the rust.

Any polishing agent (silver polish, etc.) usually has oxalic acid as an ingredient, which digests rust. That will remove the oxide rust - but the blemish remains.

But damage to the surface remains, and can only be removed by polishing/sanding/honing the blemished area so it's not so obvious.
