It is a very therapeutic - scraping the bottom of the barrel that is - preferably a metal one and using a mettelsome implement for a grater sounding effect. It is almost better than singing in the bathroom on the annoying richta scale of bee flat major miner, it is childs play like metal pale, wooden spoon and tapping like there was no tomorrow. All this in the name of cleaning a grille well, it certainly pans out. Total nonsense but veritably putting of the inevitable. Oh no, I hear the wringing of my Mother's grammarphone.
