Tea can either warm your bones on a cold winter day or quench your thirst on a humid summer day. No matter how you enjoy your tea, you may end up with tea stains on your cups or glasses. Unfortunately, tea, like coffee, is acidic and leaves behind brownish stains that cling to a glass surface. Regular washing normally cannot remove the entire stain. You need a stronger cleaning agent to remove stubborn tea stains from glass.
Mix 3 tbsp. of baking soda with 4 or 5 drops of water to form a paste.
Dip a damp dishrag into the paste solution and rub onto the tea stains on the glass. The abrasiveness of the baking soda breaks down the tea stains, while not harming the glass.
Dissolve 1 tsp. of dishwasher detergent into 1 cup of hot water.
Place tea-stained glasses into a sink. Pour the dishwasher detergent solution into the glasses, covering the tea stains. Allow the cleaning solution to work on the stains overnight.
Pour the dishwasher detergent out of the glasses the next morning. Wash and dry the glasses. If the tea stains remain, repeat the procedure.
