Rust on kitchen knives is a familiar nuisance. Store-bought removers work, but you may not need them: simple, at-home fixes can bring back the shine without relying on chemicals. These approaches suit anyone who prefers time-tested, natural remedies—and they’re gentle on both budget and routine.
The potato fix
It may sound unlikely, but a potato can be a dependable ally against rust. Insert the knife—or any small metal item that needs cleaning—into a raw potato and leave it for 24 hours. After a day, take it out and wipe the surface with a coarse cloth lightly moistened with oil. The oil helps lift any remaining residue and adds a protective film that discourages rust from returning.
Why it works
The key is oxalic acid naturally present in potatoes. It reacts with rust—iron hydroxide—helping to break it down so it releases from the metal.
The onion alternative
If you’d rather avoid the potato method, reach for an onion. Rub the blade—or another rusty surface—with fresh onion juice and let it sit for a few hours. Then wipe away the rust along with the juice. This works because the acids in onion juice interact with rust, making it easy to remove.
When to use these methods
Both approaches are best for rust that hasn’t penetrated deeply. They’re safe, economical, and, most importantly, effective. Try them and see how quickly everyday ingredients can restore your favorite kitchen tools—no commercial cleaners required.
