It's best to buy your steel wool from a craft or art store, usually they have it in the woodwork, sculpting or clay section.
Almost all steel wool bought from the hardware store will have oil on it (to reduce friction and, therefore, the fire hazard when using it for it's original purpose - as a way to abrade another metal surface). This oil will ruin the surface of Claybord.
