There’s a kitchen trick that’s been floating around for decades and sounds like an urban legend. Rub your hands against something made of stainless steel under running water, and the garlic smell on hands supposedly vanishes like magic. In fact, there’s even a product sold just for this: a bar shaped like soap, but made of metal. The question is whether it actually works, or whether it’s just placebo with a shiny finish.
The trick in one sentence: rub your hands against any stainless steel object under cold water for 10-15 seconds. That alone should fade the smell quite a bit. Moreover, you don’t need to buy anything special either, since a spoon, the faucet, or a pan will do.
How to get rid of garlic smell on hands
- After chopping garlic or onion, turn on the cold water tap. Hot water can actually help set the smell into your skin.
- Grab any stainless steel object within reach: a spoon, the faucet itself, the sink, or a pan.
- Rub your palms, fingers, and especially your fingernails against the metal surface, as if you were lathering up with soap. Do this for 10 to 15 seconds.
- Rinse with water. If the smell lingers, repeat the process or finish off with regular soap.
Why it (kind of) works
Garlic and onion smell so intense because chopping them releases sulfur-based volatile compounds, like allicin. In fact, these compounds bind to the proteins in your skin. The theory behind the steel trick is that the chromium oxide layer coating stainless steel reacts with those sulfur compounds. As a result, it “traps” them on the metal’s surface instead of leaving them on your hands. In other words, the smell doesn’t disappear — it just changes owners.
It sounds convincing, and the chemistry behind it is plausible. However, here’s the awkward part: solid scientific evidence is actually pretty thin. When it’s been tested more rigorously, according to BBC Science Focus, results have been mixed. Steel does remove a good chunk of the smell right after use. Still, a faint trace of garlic mixed with a slightly metallic scent can remain. Meanwhile, the original odor tends to creep back within a few minutes, especially if some time has passed between cooking and washing your hands.
Bottom line: it’s neither pure magic nor a total myth when it comes to garlic smell on hands. Think of it more as a quick patch that helps when you’re in a rush before shaking someone’s hand. Therefore, it’s not a replacement for an actual wash with soap. Still, since you’re rinsing under cold water anyway, there’s really nothing to lose by trying it. Worst case, your hands end up just as clean as if you’d only used soap.
On top of that, if your kitchen problem is tears rather than smell, here’s why chopping onions makes you cry so much.
