Good morning,

just passing on a tip, if you are like me and clean your oven about once a year when you nearly pass out on opening the door, try this.
Oven Pride has a plastic bag in which you place the racks and leave overnight in half the liquid, the other half you sponge over the oven and leave overnight.
next morning wash clean and voila, you have a sparkling oven with very little elbow grease.
