White vinegar is cheap and chemical-free. Best of all it can make your kitchen sparkle. You can clean your refrigerator so it will look good enough to eat out of! Mix half white vinegar and half water to wipe the shelves and walls. For stained or heavily soiled areas let it sit awhile then wipe off with a wet cloth. To clean stubborn splatter in your microwave, mix 1/2 cup each of white vinegar and water in a glass bowl. Place in the microwave for 2-3 minutes on high (until it boils). Let it sit for about a minute with the door closed, the wipe the interior of the oven with a soft cloth or sponge. White vinegar is great to clean wooden cutting boards too. Germs and bacteria can build up quickly in the porous wood so if you spray your boards once a week with it then rinse thoroughly with water and dry completely before using.
