What is steel wool and what kind of shop can I get it from?
steel wool is an abrasive material, a bit like a ‘pink bat’ as used in household insulation. Just imagine candy floss made of very fine steel. You hold it in your hand and use it like a sponge. It is great for removing rust from metal objects. Steel wool is sold in most hardware shops. Bunnings sells it in the paint department. It is fairly cheap as well.
