Redecker’s 100% recyclable, durable double-layer copper cloths are gentle on most surfaces and tough on stains, stuck-on food, and rust. Great for bathrooms, kitchens, automobiles, silverware and more. And they last forever. We especially like that they are a bit softer to hold than pure copper scrubbers, and the form factor allows you to use like a cloth (for smaller crevices) and fold it up and use like a sponge.
