Garryflex Abrasive Cleaning Block 120g (Grey)
Made for removing light rust or tarnish and restoring a bright metal finish particularly to cast iron and steel.
The Garryflex is a block approximately 80mm x 50mm x 20mm made of a rubber like compound impregnated with silicon carbide abrasive particles.
Available in medium 120g (Dk Grey) and fine 240g (Brown).
The blocks can be used dry but for best results use a lubricant such as water, paraffin, oil, camellia oil etc. (Do not use WD40 or similar as these tend to eat away at the compound).
Garryflex blocks can also be cut to shape if necessary.
