If you've ever been singed while oiling your grill, you'll appreciate Martha's special technique. Take a clean rag, fold it into thirds lengthwise, and roll it up. Tie one end with cotton twine, and wrap the remaining length of twine securely around the rag, forming a sort of handle. Place it upright in a covered container filled with a little vegetable oil -- Martha uses a recycled plastic quart container. Not only will it prevent injury, but it will also be within convenient reach.
