Coarse Sandflex blocks are tougher that other Sandflex types, making them very useful for heavy rust removal. This product cleans scale and discoloration right off metal surfaces.
Before using Sandflex: Do not use on painted surfaces unless you are attempting to remove or "scruff" existing paint; do not use on coated or plated surfaces; always test Sandflex in an inconspicious place before using.
Sandflex is a simple, multi-purpose tool that can be used in both manufacturing facilities and home. Make your belongings shine like new, whether it's polishing pots & pans, cleaning grease off grills, or removing rust from metal surfaces of machinery.
