Who likes cleaning the oven? Not me. I have double ovens...which are self-cleaning (LOL) though I only use that function very occasionally. A non-stick liner is the perfect solution for keeping the 'floor' of the oven clean. Made of heavy-duty non-stick coated fabric...even the most stubborn cooked-on spills simply wipe off or rinse away. They last for many years (I've had mine for well over five years)...withstand high temp's and are easy to remove for cleaning. The liners are available at kitchen shops and on-line...and can be trimmed to fit most sized ovens. It works for me! (This liner cannot be placed on the floor of ovens where the heating element is hidden in the base. It should then be laid on the bottom rack.)
As for the racks, I'll share my easy 'no scrub' method for getting them shiny and looking new again. I remove them before the self-cleaning cycle since it discolours them.
- Put the racks in a large black garbage bag...outdoors.
- Spray them well with oven cleaner.
- Tie the bag shut tightly.
- Leave overnight (at least 12 hours).
- Hose them down.
- Wipe clean.
