How to Get White Plastic on Kitchen Appliances White Again After Turning Yellow With Age

White plastic kitchen appliances give the room a pristine and tidy appearance when new, but the plastic often begins to yellow over time. This is a normal reaction to things in the environment, such as light, dirt and even cigarette smoke. Since it's not practical to soak kitchen appliances in water, other measures must be taken. These involve using products that eliminate the buildup and restore the appliances to their original bright white shade.

Wash the exterior of the appliances with a sponge dipped in warm water and dish detergent.
