1/2 teaspoon of washing soda*

* Depending upon your location * items may be tricky to find. Here in Windsor & Essex County it is difficult to buy everything. First try the household cleaning aisle in the supermarket, tucked high or low on the shelf, a health food shop, the local pharmacy or the hardware shop. They may have to order it for you or failing that everything can be ordered on the internet.
