When tea and coffee cups get brown rims, it can be difficult to remove them with ordinary washing-up liquid. Here's a guide and some great tips to help clean your cups and remove those pesky stains:

  1. Lemon juice: Lemon juice is a natural cleaning agent that can help remove brown marks on tea and coffee cups. Squeeze the juice from a lemon and rub it gently on the stained areas. Let it sit for a few minutes and then rinse the cup thoroughly. The lemon's natural acid helps break down the stains, leaving the cup fresh and clean.

  2. Baking soda: Baking soda is an effective cleaning agent that can be used to remove brown streaks. Make a paste by mixing baking soda with water and apply it to the stained areas. Leave it on for a few minutes and scrub gently with a soft brush or sponge. Rinse the cup thoroughly afterwards. The mild abrasive properties of the baking soda help remove the stains without damaging the cup.

  3. Vinegar: Vinegar is another natural cleaner that can help remove brown stains. Fill the cup with a mixture of equal parts vinegar and water and let it sit for a few hours or overnight. Rinse the cup thoroughly and wash it as usual with washing-up liquid. Vinegar helps dissolve the brown stains and leaves the cup clean and fresh.

  4. Coffee and tea cleaners: There are also commercial cleaners specifically designed to remove stains and deposits from coffee and tea equipment. These products can be found in supermarkets or specialty stores. Follow the instructions on the product carefully and apply it to the brown spots. Rinse the cup thoroughly after using the cleaning agent.

Always remember to read and follow the instructions on the product or carry out a test on a small part of the cup before using the cleaning agent on the whole cup. In this way, you avoid any damage or discoloration.

With these products and methods, you can effectively remove the brown stains and restore the original beauty and shine of your tea and coffee cups.
