Although making a cup of tea with a tea bag, boiling water and a mug is quick and convenient, some prefer to brew tea in a teapot in the traditional manner. However, over time, the tea leaves can stain the tea pot. Although the stains usually don't affect the flavour of the tea, a stained teapot is unsightly and may detract from the enjoyment of brewing a cup of tea.
Fill your stained ceramic or glass teapot with boiling water. Cut a lemon in quarters. Squeeze the juice of one of the lemon quarters into the boiling water, then add the squeezed lemon wedge to the boiling water.
Stir in 1/8 cup of baking soda, then allow the teapot to sit overnight. If the stain hasn't been removed or if the stain is on the outside of your teapot, mix a small amount of lemon juice and baking soda into a paste about the consistency of toothpaste.
Dip a damp cloth into the paste and scrub the stain. Rinse thoroughly.
Measure 1 cup of baking soda into your stainless steel teapot, then fill the teapot with water. Place the teapot on the stove and bring the mixture to a boil.
Remove the pot from the burner and leave the hot water in the pot until the pot is hot, but cool enough to touch. Pour out most of the mixture and scrub the inside of the teapot with a brush or a dish scrubber.
Make a thicker paste of water and baking soda if the stain is still visible. Scrub the inside of the teapot with the baking soda paste. Use the same paste to clean any stains on the outside of your stainless steel teapot.
Wash the teapot with dish detergent and warm water. Rinse the pot thoroughly to remove all traces of baking soda or detergent.
A mixture of half household vinegar and half water may remove stains from fine china. Spread the mixture on the stain and allow it to soak for 10 to 15 minutes, then rinse thoroughly. Clean stains from china or porcelain teapots with baking soda or a paste made of baking soda and water. Avoid using lemon juice on fine china or porcelain. If the inside of your teapot is a mess and hasn't been cleaned for ages, fill the teapot with hot water and drop in a denture tablet. Leave it in the teapot for at least four hours, and as long as overnight. Scrub the teapot and the deposits and corrosion should disappear.
Never place your teapot in the dishwasher. Never clean your teapot with harsh chemicals.
