Copper is because it is naturally both soft and tough — it'll quickly remove grim on a variety of surfaces, from cookware to grill tops, without scratching

Unlike steel wool or stainless steel scrubbers, copper scourers won't rust or splinter, so they also won't destroy your hands

Copper also has natural antimicrobial properties so you can worry less about spreading around germs — harbor any bacteria, so no funky smells
