Calling anything related to cleaning my "favorite" is a bit of a stretch. That said, I'd be absolutely lost without a few of these non-abrasive scrubbing pads beneath my sink.
I was first introduced to these particular scrubbing pads by Tane Chan of San Francisco's The Wok Shop. She slipped them into my bag after we'd been chatting, insisting that they were the best non-abrasive scrubbies I'd ever find anywhere. And of course she was totally right.
While the sponges looks like they are made from something metallic, they're actually a plastic mesh cover wrapped around a standard sponge. The plastic is fairly soft and flexible, but the pads scour the crusty, caked-on bits from my pans like a pro.
I've used these scrubs on non-stick pans, cast-iron skillets (without soap!), enamel-coated dishes, and regular stainless steel pots. They've never left scratches and seem to work equally well on all surfaces.
Finding these exact same pads is a trick. So far, I've actually only seen them at The Wok Shop, and the only place I can find online to order these scrub pads is (You guessed it!) The Wok Shop itself. Amazon does carry another pad that looks similar:
• Scrub Pads, $1.50 for a set of 3 from The Wok Shop • Nonstick Scrubbing Pads from RSVP, $8.70 for a set of 6 on Amazon
Do you have a favorite non-abrasive scrubbing brush?

Even I use the same,,they are very effective,,.:)
I use very similar ones and I find them at the Dollar Tree! They work wonderfully, and the metallic sparkle perks up a kitchen and hides sponge gunk.
i recently switched from using scrubbing pads/sponges to using simple bar cloths/washcloths. they work brilliantly and don't harbor funk. that is, i'm sure they would, but they are in constant circulation through the wash - use for one load of dishes, toss in the "dirties" tub by the washer, and throw them into the next load (with some exceptions for delicate laundry).
I also use washcloths for most stuff and natural fiber sponges for the tough stuff. The natural fiber ones aren't super abrasive but they do work pretty well when combined with a good citrus-oil based cleaner. I keep my kitchen pretty green so I make my own eco friendly all-purpose cleaner, costs me about a dollar a batch and works wonders on things like my cast irons and the stove. Definitely reduces the need for elbow grease.
