You have stubborn stains that your detergent just can't remove, this nightmare will remove them! Me wear this on my bench grinder at my shop, I used to carry regular wire brushes too often and thought a twisted wire like this would last me longer, I think it will last a few minutes longer Rust, paint, dirt, grease, everything all you have to do is barely touch your part or work the spoked wheel and it's gone! Impressive is the speed at which it removes years of rust down to bare metal in seconds! Always remember to wear safety goggles and before to wear gloves to everything. It's fantastic!
