The tiny, brilliant $10 kitchen tool that set me (and 11,000+ Amazon fans) free

The arrival of spring always results in my calendar being filled with picnic and potluck invites. That means prepping plenty of my go-to offering: a colorful kale-and-red-onion salad. Since my friends tend to gravitate towards high-octane comfort dishes, I realized (via my last-minute laziness) that a clean green salad is always a welcome addition (to cut the richness of the rest). Easy win!

Of course, chopping red onions an hour before a social event presents its own challenges — because alliums don't just wash off. They soak in and scent skin like the evil twin of a lavender bath. You can wash and wash, and still, the scent lingers, leaving you unintentionally wearing Eau de Onion.

That is, until I found this brilliant little treasure. Known by a number of names, the Rub-a-Way Bar is some sort of miracle. It’s a soap-shaped doodad made of lightweight stainless steel that magically and instantly removes the smell of onions (and garlic, and shallots, and scallions) from your skin. Just rub it in your hands as if it's a bar of soap with or without water, and all signs of aromatics are gone. I swear.

The science behind this transfer of scent is beyond me, but for those who understand, apparently, it has something to do with steel molecules binding with the (stinky) sulfur molecules on hands, thereby lifting them away. That sounds like something that should cost some cash, but this lifesaver retails for just $10.

The first time I used the odor remover bar, I thought I was imagining the effects. I called my teenagers into the kitchen to sniff (they did not budge, because when you say, "Come in here and smell my hands" to teenagers, turns out they don't even actually respond). I marched to the living room and forced the issue. And I heard the magic words. "What? I don’t smell anything." Followed, of course, by: "Move, please, Mom. I can’t see the TV."

Back to my savior kale salad: During the holidays, I make it sparkle with fresh pomegranate; in the fall I use dried cranberries, and at the peak of summer, cherry tomatoes. The secret sauce (quite literally) is a dressing made with good olive oil, fresh garlic and a sweet balsamic vinegar. Style it with some long slivers of red onion on the very top, curving toward each other. And then, of course, don’t forget to "rub away" that last onion infusion with your brilliant bar

You'll arrive at the party smelling fresh as a rose.

Seems I'm in good company; this thing has racked up thousands of perfect ratings.

"This actually works," wrote a home cook who likes to use onions and garlic. "I would say the only quicker way to get smell off when not using gloves is rubbing alcohol. I have also used this when coming back from the cigar lounge. It helped to pull the smell off of my hands."

"Gets the stink off!" exclaimed another convert. "I've used it to get onion and garlic smell off my hands after chopping and preparing meals. If it's a smell you can't get off your hands, use this — it works! Should last forever!"

"Simply amazing," reported this rave reviewer. "Before this product, every time I chopped garlic, no matter how many times I washed my hands, showered, etc., it always took about three full days for my hands to not stink of garlic. One hand wash with this nice-feeling metal rub, and the odor is gone. Why didn't I buy this years ago?"

"I cook a lot in the morning before work — preparing a slow cooker," shared a shopper. "Often, while sitting at work, I put my hands up near or on my face. Despite washing them, my fingers often smelled like garlic, salmon, onion, etc. Not enough that other people could smell it, but distracting enough for me! I tried using this, and would smell my fingers before and after using this stainless steel soap — and it really DOES remove all the odors! Just wish it was a TAD smaller in size."

A final fan wrote: "This works wonders ... The only negative is it can't get under your nails."

P.S. I started my love affair with these smell-removing bars by purchasing this understated Norpro version from Amazon — it's even cheaper!
