Ceramic cups and bone china plates often acquire a tawny stain with the passage of time. Whether it is because of certain food or beverage served in it or because they are so old, that time has left its impression on them in the form of stains. Check out how you can use baking soda from that favourite antique bone china crockery of yours.
Wash your bone china cup with soapy water to remove superficial impurities. Sprinkle some baking soda on the wet bone china cup. As the baking soda clings to the dampened cup, rub the thin film of baking soda paste all over the cup. Focus on the areas where the stains are stubborn. Scrub for sometime so that the stain is removed. Rinse the cup with warm water to remove baking soda residue. Turn your bone china cup upside down and let it air dry. Repeat the procedure with some more baking soda if the stains are not completely removed.
Add mild dishwashing liquid to hot water with which you have filled a sink. Add a cup of white vinegar to it. Place your bone chine plates in the sink. Let it soak for 15 minutes. Now wash each plate using a sponge. Lay the wet plates on a sheet of towel, ensuring the stains face up. In a bowl, make a thick paste using baking soda and water. Scoop the paste with a toothbrush and scrub the stains. Leave the baking soda paste on the stains for a few minutes. Rinse the plates using hot water and place them on a rack to air dry.
You may even use 20% hydrogen peroxide for removing coffee or tea stains from bone china cups. Use mild scouring powder for removing marks left by metal utensils on your bone china.
