Nano Sponge Cleaning Sponges. Supersized Everyday Heavy Duty Household Kitchen and Dish Sponge. 2 Pack. 6 x 4

last a long time because they are washable in either the dishwasher or washing machine

It works very well with two different sides for cleaning easier, one smooth the other rough

This handy cleaning sponge is versatile and heavy duty without being cumbersome. I have had multiple sets and cannot fathom going without one at hand. Not only does it gently wipe surfaces it also scrapes without scratching. Highly recommend.

These sponges do perform better than regular cellulose sponges, as it relates to not smelling after frequently being wet and dry. They are rather large for dish washing, but do an excellent job once you get used to their size. The nanotechnology is different from microfiber but to the general user cleans the same. The "scrubby" side of the sponge does work very well removing baked on food from pans. However, I suggest you do NOT use the sponge to clean cast iron skillets. The skillet was cleaned very well. But the sponge was no longer usable. It virtually removed all the oil from the cast iron. I was not able to clean the sponge after that and it had to be thrown out.So, for the price they do perform well, but take care of the type of dirty items you use the sponge to clean. You may need to designate specific sponges for specific jobs.

Ordered these after ordering & loving 2 sets of the nano towels after hee-hawing whether to try. Cleaning with just water? Not so sure about that, but I stand corrected. These are the best sponges ever! I've been using the sponge for about a month now & am simply amazed. The sponge is larger than normal, which takes a little getting used to. Now I actually prefer the larger size. The sponge wrings almost completely dry & air dries quickly. I live in a hot & very humid area & unbelievable that there is no odor at all, ever - unprescedented! I don't use a dishwasher, just simply hand wash every now & then with anti-bacterial soap & air dry. Very easy to wring out into a very small ball & springs back to full size readily. I have small hands, so this is a big plus. Outstanding to wash Instant Pot stainless inner pot & have cut down use of barkeeper's friend to remove rainbow & spots with barely a swipe, little scrubbing. The pot is almost dry after wiping & ready to be stored after washing dishes. I use for hand-washing dishes, wiping countertops, just everything. The set I received is grey on one side & looks like the same material as the nano towel. The scrubber side is non-scratch but powerful. I will definitely buy more of these for all around the house & highly recommend. I originally balked at the price, but these are well worth the cost.

It used to work well but was getting a little worn, so I first checked when the last two had been ordered. Found out that was back in 2017 and had daily usage. So went for two packs now.

These sponges are the best! Seriously. They WILL NOT smell if you rinse them after use and spray something like lysol on them every so often. My wife has the nose from hel_ and can smell anything (not always a good thing though LOL) and also has zero complaints. Worth the price.

I really, really wanted to love this sponge. I’m a big believer in reducing chemicals in the home & our overall impact on the environment. The thought of going free from cleaning products was appealing, but honestly I didn’t find that possible with this sponge.Our first use of the sponge was after a dinner that was cooked in a skillet with a glass lid. We tried the ‘only hot water’ suggestion and were disappointed. While the sponge did a great job of removing the cooked on food bits from the pan, it also felt greasy during the cleaning. Even with copious amounts of hot water, we were not able to get the glass lid to be grease free. At one point my husband commented on whether the sponge was actually an environmental choice if it required the use of more water to clean without cleaning products... good poimt, actually.Not willing to admit defeat, we put the sponge to the test a few days later on a greasy pan from bacon. This was a double whammy - the sponge and pan felt greasy, and the little bacon bits got buried in the mesh on the scrubbing side. Big bummer.In the end, I really didn’t find it possible to use them with only hot water. In our case, we are sticking with environmentally safe ‘green’ dish soaps and cleaning products as they get the job done with less water.As for the sponge’s antibacterial properties, this applies only to the sponge itself. It should be noted that you still need to use some type of disinfectant if you want to sanitize a surface (e.g. cutting boards). As for disinfecting the sponge itself, the trick is the same with these as any other sponge: 2 minutes in microwave, throw it in the d/w, or sanitize with vinegar.PROs: Durable, good size, absorbent material, will probably last longer than other spongesCONs: Despite claims, food does stick to the scrubbing side, not great at cleaning greasy food residue, still needed to use dish soap, or disinfectant for counters.
