With so many kitchens decked out in stainless steel these days, you'd think there'd be more options for fantastic made-for-stainless cleaners on the market. If you've ever shopped for said products though, you'd probably agree that the choices are pretty dismal. I've tried a couple different aerosol sprays, but they were so chemical-laden I always wound up with a splitting headache after using them and the nagging feeling that inhaling the fumes was generally just a bad, unhealthy idea. So I was thrilled to see this post on unplgged.com recently, which outlines some simple mild-but-effective solutions to get stainless steel sparkling:
For light cleaning (like fingerprint stains and little smudges), try a window cleaner. To amp up the cleaning power, you can also use vinegar (seriously, what can't this stuff be used for?!) and buffing spots gently with a microfiber cloth.
Bar Keeper's Friend-which I've been meaning to try for years now after hearing so many people rave about the stuff-is also said to work wonders on stainless steel, and unlike some of the other, more abrasive powder formulas out there, this one won't leave scratches.
For heavy duty cleaning, use Soft Scrub with a washcloth on the more stubborn spots. You can also get in there with a Magic Eraser, but be sure to do so with a light hand, and don't go against the grain of the metal or risk leaving marks.
Commenters on unplgged also attest to the effectiveness of furniture polish (one specifies the "orange oil kind") on stainless steel, and some also suggest rubbing a light coat of olive oil onto the surface after it has been cleaned, to prevent future smudging.
