After cleaning with warm water and soap, wipe down with vanilla essence or leave an open packet of bicarbonate of soda in the fridge.

Tires should be inflated to the pressure recommended for your vehicle; this information is often printed inside the door frame or in your owner's manual. For every 3 pounds below recommended pressure, fuel economy goes down by about 1 percent. Tires can lose about 1 pound of pressure in a month, so check the air pressure regularly and always before going on a long trip or carrying heavy loads. Underinflated tires can also detract from handling, safety, and how long the tires will last.
