Oh what a cleaver idea. I only recently saw these on the net, so I bought some. I actually like them. they work great on the glass baking dishes, cake pans, and so much more. They are easily rinsed. Said to be able to put into the dishwasher for top clean.

Doesn’t beat a traditional sponge/scourer; you need a lot more elbow grease to remove baked-on food, plus it doesn’t sud up well so you need to use more dishwashing liquid. However the product itself is super easy to clean as you can just throw it into the dishwasher, and it comes out as new again. As it’s silicone it’ll last for forever, so much more environmentally friendly than sponges which you have to replace often. So overall, it’s good for light cleaning, not for heavy duty stuff.
