Scotch Brite Heavy Duty Sponges work great to get grease and stuck-on food off pots and pans. I just add a little bit of dish soap and they work great! I haven't experienced any cons with them at all and would definitely recommend them to others!
These sponges last for a long time! I feel like the back green buffer part really cuts down caked on grime. It's at a great price point -- under 3 dollars for one sponge. I've always liked this sponge and I always buy extras when I need them. Great choice!
