MIGHTY SALT

Don't you get irritated by tea and coffee stains on your favourite mugs?

The most effective way I find in getting rid of these stubborn stains is by using salt.

Wet your favourite mug.  Then use a teaspoon of salt and start scrubbing the tea or coffee stains.

Rinse well.  Repeat if required.

I've even tried using salt on crystal wine glasses and it works perfectly.
