This is the only cleaning sponge I use and in the few times I have forgotten to buy them, I have called the husband and asked him to stop and pick it up on the way home. So over the ten years we have been married he has brought home many vatiations of my preferred sponge, which went into my collection under the sink, because I refuse to use them. But now he knows exactly what kind of cleaning sponge to buy and the collection under my sink is getting smaller beacause he uses them for washing the car.
These are the only sponges we use. tough enough to tackle the heavy dirt, yet gentle enough to use on my non-stick coatings. we even use it on our glass bake-ware.
