I LOVE the green heavy duty scrubbers. Scotch Brite is the only brand I buy. They tackle anything I throw at them. I use them at work also while doing dishes. You ought to see the dishes/pans/coffee tea pots and stainless steel sparkle! I'll stop using them, when you pry them from my cold dead fingers!!
I like these sponges as it is 2 products in one. I don't have to have a separate thing to scrub off tough food stains and then another sponge to use for the non stuck stuff. I just flip the sponge over. Works well and lasts for quite awhile.
Although there are a lot of packages of "bargain" sponges available, I always choose Scotch-Brite Heavy Duty scrub sponges. They make kitchen scrubbing chores easy. They are durable and long-lasting. Trust 3M to make a winning product.
We have very hard water at our cabin and it's very difficult to wash and scrub pans and dishes. The sponge holds soap for a very long time while the scrub part is harsh enough for pans but gentel enough for dishes. I love it.
