A great alternative to using disposable scrubbers is a non-abrasive Redecker copper cleaner or copper cloth. Great for cleaning pots, pans, sinks, ovens, ceramic stovetops, glass, stainless steel, and more without scratching. They are made with 75% Copper Threads and 25% Polypropylene Yarn. Many scrap metal recyclers accept items that are at least 50% metal to be recycled - check with your local scrap metal recycler!
