Ease of cleaning is well worth considering at the outset. Stay clean liners resist dirt build-up but pyrolitic cleaning is the ultimate. It burns off all baked-on debris at 500°C so that all you have to do is sweep out the resulting ash. Look out for ovens with a steam cleaning facility, too, and remember that some ovens have removable inner doors that are easy to clean.

When shopping for a new washer, look for a front loading (horizontal-axis) machine. This machine may cost more to buy but uses about a third of the energy and less water than a top-loading machine. With a front loader, you'll also save more on clothes drying, because they remove more water from your clothes during the spin cycle. Look for the Energy Star label.

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.
