We must return to the pot scourer which, by the way, is a form of armament. It is a very useful weapon and I have frequently used it myself. May I explain to the Committee the use of a pot scourer? One takes a pot—I will come to rolling pins in a minute—and, if the pot is not very clean, one takes the pot scourer, whether fully-manufactured or half-baked, and hot water—boiling water, if available—and scours and scours and scours. One of my hon. Friends argued with me that a mop was better than a pot scourer, but I have used both and I am bound to say that I come down on the side of the pot scourer.
