Handbags   (The sad, the bad and the ugly. Non-productive stuff here.)

The simplest way to remove tannin stains is Bicarbonate of Soda. Use a sprinkle on a damp cloth or piece of kitchen towel, and rub the stains. Then rinse and wash...no taste and cheap. Two heaped teaspoons in a teapot topped up with boiling water and allowed to cool, rub around with a gentle sponge scourer and be prepared for all the gunge it will move. Again rinse and wash as normal. you can soak cups in the same way, but it is quicker just to rub with a damp cloth....... No scratching, funny taste or expensive.
