Remove rust.? I have this bowie knife from at lowest possible 15-20 years ago....

I have this bowie knife from at lowest possible 15-20 years ago. So at the supermarket what chemical can i buy to remove this VERY deep rust. If coca cola works will coca cola stain the steel. how long do i leave the axe submerged in coca cola soda for will it damage the wood on my blade please minister to this bowie is a one of a kind beauty i would resembling to use it for hunting and fishing. It is stainless steel.
I've never cared for the coca cola thing. It lately doesn't work for me. I use SOS pads. I scrub all the rust stale, then rinse and dry it . After that, I oil it near one tablespoon vegetable oil, rubbing it in ably. Then I get a terry towel and buff it. if it's rusty it's not stainless if a magnet sticks to it it's not stainless buy some navel jelly at the hardware store to remove the rust
For starters, your pierce is not stainless steel. Stainless steel doesn't rust. The blade is probably carbon steel. Soak only the blade in coke. Let it sit a couple days and check it. Just preserve at it. Fine emery cloth can be used to sand off the rust. Polish with Scotch bright pad for a smooth even finish. Best household product I have used to remove rust is...Toilet Bowl cleaner. Just scrape bad any heavy rust...them place the knife blade within a glass with toilet bowl cleaner. You can leave your job it a hour or two.but don;t leave it too long. Rinse it off well-mannered and use a baking soda to counter act the acid...after that apply rather WD-40. You can use some steel-wool to shine it up.
Answers:    Without knowing where at all you hear some myth about Coke, I suspect you are over stressing. The Rust has already worn out the blade, and I doubt you can do much more harm with carbonation, citric tart, coloring and fructose.

No offense but STAINLESS must have been subjected to the most extreme conditions on the planet, to rust.

Given "ONE OF A KIND" I assume it have some heirloom value, or assumed value to you, beyond it's intended functionality. Why wouldn't you assume afterwards, to take it to someone involved in the process of restoration?

Just my two "sense"
If you or a friend has a buffing gearstick on your grinder.do it man. Just be careful the wheel doesn't throw it at you. I verbs most of the rust off my tools with the rope wheel...and just shine...adjectives the best guy ..nite WD-40 will do it... it's very cheap and you can buy it on any hardware or DIY shops .
