Burnt-on food and grime can be completely removed with the Dremel Versa extreme scour pad. The silicon Carbide abrasive is great for the toughest cleaning tasks on hard surfaces. The Multi-Purpose surface can be used in wet or dry applications to clean grill grates & stove grates, rust from metal, oil/water/paint stains from concrete. Do not use on delicate or soft surfaces as they could be scratched.
