3MExtra Large Commercial Sponge – Durable, Highly Absorbent Cleaning Sponge for Heavy-Duty Tasks – Pack of 5

Traditional cellulose sponges. Nice and big and thick. Great for tiling work. Love them.

Sturdy, well-made, terrific absorbency, durable, no off-gassing. Nothing weird. Just like the big yellow sponges I used when I was a kid about 100 years ago.

Just the right size and absorbs liquid well. Not much else to say.

Sturdy and soaks up liquid better than most other sponges

I needed sponges for my incubator to increase humidity. I tried the polyester type sponges (specifically those hourglass shaped sponges), they push water around rather than absorb it unless you squish them and kind of by suction of them going back to shape they pull up the water. No no no.I got these and THIS is what I need. If you set them in water they slowly soak up the water into the sponge all by themselves. This is what is needed in an incubator if you're going to put a sponge in the water well. It HAS to suck up the water all by itself and keep itself moist at all times so the air moving over can evaporate the water in the sponge and as that moisture leaves, the sponge pulls in more to replace it. That is how it works.These are thick, durable feeling and suck up water really great. Since they seem durable and I use sanitizer in my incubator water, they should stay in good shape and nastiness free for a long time. The price is good enough that I can replace them if they get clogged with hard water deposits every couple years. And I might not even have to do that if I change them out and soak them in vinegar from time to time to break down any deposits.I'm really happy with these. So much so that I just ordered another pack to have enough to change them out and soak them in vinegar from time to time.

These are the best for washing your floor! It’s hard to get big sponges at the store now, so I’ve had to resort to ordering them

I used these sponges for lithography printing, so they were used pretty intensely and started to flake after some weeks of use, but honestly, they work really well and feel really great. Be sure to rinse them out before your first use because there is some sort of soap that they are presoaked with.

Like using on floors
