If you practice your golf short game, you probably have a shag bag for holding and collecting all the golf balls you have. After you've hit your shag balls a couple dozen times, they will be coated with grass and mud. You will want to clean the golf balls, because the mud and grass stuck to the balls introduces error into every practice shot, thus diminishing the quality of the practice you're getting. Cleaning golf balls manually really sucks. What to do?

Simple. Fill your kitchen sink with hot water. Pour the golf balls out of the shag bag, into the sink. Add Cascade dishwasher detergent. Let stand for an hour. Rinse. The grass and mud will be magically removed from the surface of your shag balls, without manual labor on your part.
