This amazing block is like an eraser for rust! Easily remove rust and stains from metal surfaces without the use of liquids or chemicals. Sandflex blocks are made from carbide grit , imbedded throughout a semi-flexible rubber compound. Since carbide grit is distributed evenly throughout the entire block, as the block wears, new and sharp abrasive material is continuously exposed. They also work great on stainless steel pans and sinks and remove mineral deposits from ceramic tile. A quick, clean way to clean surface rust off your metal tools. Show more
