SandFlex Hand Blocks are designed to clean and polish metal tools and objects. The grit is mixed with rubber prior to molding. As old grit wears away, new grit is exposed to keep the block working well. The blocks are available in Coarse grit, Medium grit and Fine grit. Common uses include:
- Clean rust from tools and unfinished metals
- Remove rust from outdoor equipment
- Clean stainless steel sinks, pots and pans
- Remove mineral deposits from ceramic tile and toilets
Simply use the blocks as you would an eraser. Rub firmly on the surface of the item. You may use them wet or dry. They are non-toxic.
Do not use them on painted or plated surfaces.
