Buy stainless spoons (both slotted and non-slotted) which are solid and won't bend no matter how tough the job. Also, buy several high quality wooden spoons for stirring delicate dishes like risotto (the sharp edge of a metal spoon would cut or bruise the rice).

This is a big ticket item, but worth its weight in gold. It will save so much time when it comes to simple chopping or more advanced preparations like mayonnaise. As with most things, buy quality-- it will last longer, be capable of tougher jobs, and give you less problems. To make the food processor easiest to use, leave it on the counter top instead of storing it in a cabinet.

Never use a scouring pad of any sort to remove stubborn stains or soiled areas, since these pads scratch the finish and any future soiled areas won't clean up as well, especially with the self-cleaning models. When the oven is cool to the touch, place a cloth or sponge, dampened with warm to hot tap water, onto the soiled area and allow it to sit, for about ten minutes or so, to help loosen the soil.
