[QUOTE=limpetmine;105364]You should store your rags and sponges with BLOicon and other cleaning agents in a metal tin, sealed from air. Rags have been known to spontaneously combust (catch on fire) from the chemical heat generated. QUOTE]

This is a real danger. Last summer my brother, having used BLOicon f/the 1st time, threw the rags in a metal waste container in his shop, which was, fortunately not attached to his house. The result was that, shortly after midnight, he was awakened by a neighbor who informed him that the shop building was ablaze. It was a total loss, amounting to just under $100,000 US. Be VERY careful.
