Kitchen Sponges

Published May 2019

How we tested

We were in the test kitchen, making scrambled eggs without oil or butter in stainless-steel skillets over high heat. The eggs stuck to the pans and made terrible messes. The test cooks working around us kept shaking their heads, no doubt wondering why we hadn't switched to nonstick pans or tossed pats of butter into the skillets. We just smiled and ignored them.

We wanted those eggs to stick to the pans. We'd just started working on a review of kitchen sponges and needed to use them for some challenging cleaning tasks. As anyone who's ever goofed up their scrambled eggs knows, getting these skillets clean would be tough.

What We Tested

Several major brands had multiple options for all-purpose sponges, so we conducted a two-step preliminary test: cleaning onions and sticky, cooked-on barbecue sauce off skillets and washing delicate wine glasses. We eliminated the lowest performer from each brand. Our final 10 sponges varied considerably in price, from about $0.70 to about $6.00 per sponge, and came in a wide variety of designs and materials.

How We Tested

We expect a lot from a kitchen sponge and tested accordingly, using them to clean nonstick, traditional, and cast-iron skillets containing a variety of cooked-on foods; mixing bowls with sticky biscuit dough; stained carving boards; cheese-smeared box graters; dirty chef's knives; fragile wine glasses; and small measuring spoons. Throughout testing, we controlled both the water temperature and the amount of soap used. Finally, we purchased three additional copies of each sponge and sent them home with staffers for several weeks of use in their kitchens.

Some sponges were ineffective and sometimes downright unpleasant to use. But many performed well, and several really impressed us. Our favorites were more versatile, stayed cleaner longer, and made quicker work of tough messes, such as those pesky stuck-on scrambled eggs.

No Two Sponges Were the Same

When we think of a kitchen sponge, most of us picture a blue or yellow rectangle with slightly rough, textured material on one side. We had a sponge like that in our lineup, as well as a few others that were a similar size and shape, but many of the sponges were very different. We grouped them into three main styles.

First, there were those familiar sponges made of fairly soft, flexible material with an abrasive pad on one side. The gentle parts of these sponges were made from either foam or cellulose. The second category consisted of sponges with soft foam cores encased in semiabrasive fabrics. We also had two outliers. One sponge was made entirely of silicone and covered with tiny bristles on two sides. The other was made of a special kind of foam. It was disk-shaped—a little taller and thicker than a hockey puck—with cutouts forming two eyes and a smiling mouth (to wipe silverware clean) plus ridged “hair” for scrubbing.

To our surprise, neither material nor design were important factors in a sponge's performance. We found sponges we liked across a range of materials and styles. So what mattered most?

The Many Styles of Scrubbing Surface

We zeroed in on the abrasive scrubbing surfaces of each sponge. The sole silicone sponge really struggled with cleaning. Its soft, flimsy bristles slid over food instead of scraping it up. The soft fabric wrapped around another sponge was similarly ineffective. It became soggy and matted, resembling the fur on a wet teddy bear. If we scrubbed with that fabric, the soft fibers became slick with eggs or barbecue sauce or whatever food we were scrubbing, so the sponge just slipped around the skillet.

The other eight sponges had better, more effective scrubbing surfaces. Two sponges had abrasive pads that looked fairly flat and smooth from a distance but were actually made from swirls of fibers that had been glued together. It didn't matter if those fibers were plant-based or plastic. With a little effort, both sloughed off cooked-on food and grime. Our favorite sponges had coarser, more visibly textured surfaces that made cleaning even easier. Two had fibers formed into loops or woven into netting, which acted like mini scrapers. The others had wide ridges, much like those of a grill pan, or were covered with bumps and valleys resembling an egg crate mattress pad. Overall, sponges with abrasive surfaces and extra texture added some force to each scrub, helping us loosen food and nudge it off cookware.

Stick to Midsize, Rectangular Sponges

Next, we looked at the size and shape of the sponges. The smallest sponges, though precise and agile, compressed under our fingers when we pressed down hard. We liked sponges that were thick enough to put some distance between us and whatever we were cleaning but also small enough to feel maneuverable. Meanwhile, bigger, puffier sponges were hard to squeeze into wine glasses or tiny measuring spoons. The most versatile sponges were midsize, roughly 4.25 inches long, 2.5 inches wide, and 1 inch thick.

We also had a quibble with the one round sponge, the Scrub Daddy. We struggled to wrap the springy, disk-shaped sponge around the blade of our chef's knife and to tuck it into tight spaces. Although this sponge was great with cookware and big pieces of equipment, it just wasn't versatile enough to be an all-purpose sponge.

A Bonus Versatility Test: Absorbency

Many people use their sponges to clean up spills on their counters, so we also tested how much liquid the sponges could soak up. Water streamed off the silicone sponge: It absorbed less than 4 grams, hardly enough to make an impact on a big spill. One foam sponge was only a little bit better, absorbing about 18 grams. Interestingly, there wasn't a correlation between absorbency and material. The rest of the sponges absorbed significantly more water, with the most absorbent sponge soaking up more than 105 grams of liquid.

You Can't Clean with a Dirty Sponge

By the end of testing, some of the sponges looked downright dirty. One fabric-wrapped sponge trapped food and never recovered from the dough test. The fibers became so matted and gunky that the fabric resembled carpet into which gum had been trampled. Food stuck to the silicone sponge despite its “stay clean” promise; no matter how we picked at or bent the sponge, those stubborn bits of food remained embedded between its bristles. Two other sponges struggled with cleaning biscuit dough. Their fairly flat woven fibers trapped dough, and when we tried to pluck off the residue, the fibers became pilled and grubby. The other sponges sometimes trapped food temporarily but were easier to rinse clean.

We also noticed some wear and tear. The netting on one sponge tore. The smiling mouth of the Scrub Daddy ripped on one side. And big patches of bristles were missing from the silicone sponge; they had been accidentally sliced right off when we were cleaning sharp knives. All the sponges were at least a little stained or discolored by the end of testing, but we think that's to be expected.

The Best Kitchen Sponge: O-Cedar Scrunge Multi-Use Scrubber Sponge

Which kitchen sponge should you buy? The O-Cedar Scrunge Multi-Use Scrubber Sponge impressed us throughout testing. It looks like a traditional, flat sponge—but it's better. Its scrubbing surface is heavily textured and gritty, so it's especially effective at dislodging cooked-on food and grease. The surface is covered with bumps and valleys, which made our scrubbing even more efficient. The Scrunge was also one of the more absorbent sponges we tested, which makes it handy for cleaning counters or wiping up spills. Our new favorite was durable and easy to rinse clean, even of sticky biscuit dough. Whether you regularly cook elaborate meals and produce a pile of hard-to-clean kitchen equipment or you just need to wash a coffee mug every morning, we highly recommend it.


We found eight widely available brands of kitchen sponges. Three of those brands offered multiple products, so we conducted an elimination round: scrubbing a cooked-on mix of onions and barbecue sauce from skillets and washing delicate wine glasses. Most products came in sets; one was sold individually. The 10 sponges in our final lineup were priced from about $0.70 to about $6.00 per sponge. We used the sponges to clean nonstick, traditional, and cast-iron skillets containing a variety of cooked-on foods; mixing bowls with sticky biscuit dough; stained carving boards; box graters that had been used to shred cheese; dirty chef's knives; fragile wine glasses; and small measuring spoons. We also sent three new copies of each sponge home with staffers for use in their kitchens. Dimensions, thickness, and water absorbency were measured in-house. Manufacturers provided information on product materials. All sponges were purchased online. Scores were averaged, and products appear below in order of preference.

Rating Criteria

Cleaning Ability: We rated how effectively sponges removed cooked-on foods from skillets and sticky doughs from mixing bowls. We docked points from sponges if they couldn't effectively clean cookware and bakeware.

Versatility: Sponges rated highest if they were flexible and maneuverable when cleaning a variety of kitchen equipment. We downgraded products that were too rigid or too thick.

Comfort: Our favorite sponges were large and substantial enough for us to grip comfortably when scrubbing hard. Lower-ranked sponges were thin or shrunk down to a small size when saturated with water or squeezed.

Durability and Cleanup: We used four copies of each sponge in the test kitchen or in home kitchens. We compared the used copies to a new copy. If sponges tore, disintegrated, or became badly stained, we docked points. We also preferred sponges that were easy to rinse clean, didn't trap food residue, and resisted odors.

The Results


Design Trifecta 360 Knife Block

Admittedly expensive, this handsome block certainly seemed to live up to its billing as “the last knife block you ever have to buy.” The heaviest model in our testing, this block was ultrastable, and its durable bamboo exterior was a breeze to clean. Well-placed medium-strength magnets made it easy to attach all our knives, and a rotating base gave us quick access to them. One tiny quibble: The blade of our 12-inch slicing knife stuck out a little.


Schmidt Brothers Downtown Block

This roomy block completely sheathed our entire winning knife set using just one of its two sides—and quite securely, thanks to long, medium-strength magnet bars. Heavy, with a grippy base, this block was very stable. An acrylic guard made this model extra-safe but also made it a little trickier to insert knives and to clean; the wood block itself showed some minor cosmetic scratching during use.


Schmidt Brothers Midtown Block

This smaller version of the Downtown Block secured all our knives nicely, though the blade of the slicing knife stuck out a bit. With a base lined with grippy material, this block was very stable. An acrylic guard afforded extra protection against contact with blades but made it a little harder to insert knives and to clean; the wood itself got a little scratched during use.

Recommended with Reservations

Swissmar Bamboo Magnetic Knife Block

This small, scratch-resistant model had a stable, rubber-lined base and could hold all our knives, though the blade of the 12-inch slicing knife stuck out a bit. But inch-long gaps between its small magnets made coverage uneven and forced us to find the magnetic hot spots in order to secure the knives. Its acrylic guard made it safer to use but harder to insert knives and to clean.

Not Recommended

Messermeister Walnut Magnet Block

This handsome block was done in by its shape—a tippy, top-heavy quarter-circle that wasn’t tall or broad enough to keep the blades of three knives from poking out. It lacked a nonslip base, and its extra-strong magnets made it unnerving to attach or remove our heavy cleaver. Finally, it got a bit scratched after extensive use.


Epicurean Standing Knife Rack 12"

This magnetic block sheathed all our knives completely, though with a bit of crowding. But it was hard to insert each knife without hitting the block’s decorative slats on way down, and because the block was light and narrow, it wobbled when bumped. Worse, we couldn’t take it apart, so splatters that hit the interior were there to stay. Additionally, the outside stained easily, and when we wiped it down, the unit smelled like wet dog.


Kapoosh Rondelle Knife Block

This model stabilized knives with a mass of stiff, spaghetti-like bristles that shed and nicked easily after extensive use, covering our knives with plastic debris. While all our knives fit securely, several of the blades stuck out, making this unit feel less safe overall. Finally, though the bristles could be removed and cleaned in the dishwasher, their nooks and crannies made this block hard to wash by hand.


Kuhn Rikon Vision Knife Block, Clear

This plastic block required us to aim each knife into the folds of an accordion-pleated insert that was removable for easy cleaning but got nicked easily with repeated use. Because we could only insert the knives vertically, longer knife blades stuck out; a cleaver was too wide to fit. The lightest model in our lineup, this block was dangerously top-heavy when loaded with knives.
