I love to bake, so I use my oven a lot... and I really, really hate cleaning it. Talk about the worst grimy, greasy, gooey, crunchy, baked-on mess. ACK!
So, I use a little help: aluminum foil.
Yes, I cook and bake with it... sometimes coating the inside of whatever bake ware I'm using so I don't have to wash and scrub so desperately when it's done. BUT, I also line the bottom of my oven with a sheet of heavy-duty aluminium foil.
This way, the grimy, greasy, gooey, crunchy bits and splats don't actually hit the oven floor. Instead, they get caught on the foil. And when the foil gets gross, I simply pull it out and toss it! EASY clean! And another great tip from the neat freak cheat sheet! ;)
Now, THAT's neat!
