A teakettle is one of those items you never really think about cleaning until your cup of tea tastes a little strange. Cleaning it could not be simpler: Fill the kettle halfway with water, then fill the rest with white vinegar. Bring the contents to a boil and set it aside to soak overnight. The next morning, pour out the vinegar mixture, fill the kettle with water and bring to a boil to remove any trace vinegar smell and taste. An added tip: Use the freshly boiled water to kill weeds so you don't waste any water. The hot water will scald the weeds to death.
