Fill a small plastic bag with vinegar, pull it over the shower-head, secure it with an elastic band and leave overnight. Fill an old spray bottle with two-thirds vinegar and one third washing-up liquid and you'll have made your own limescale-removing cleaner. To stop water on the hob from boiling over, place a wooden spoon across the middle of the pan. Or wrap the bottle in a wet paper towel and put it in the freezer for 15 minutes - it chills faster. Avert disaster by holding the wine bottle upside down between your knees and hitting the bottom with your shoe.
