Maintaining clear drains
For a non-toxic regular drain cleaner, pour ¼ cup bicarbonate of soda down the drain. Follow it with ½ cup vinegar and plug the drain until it stops fizzing. Rinse the drain thoroughly with hot water. Washing soda is also a valuable non-toxic method of maintaining free drains. Pour a tablespoon of crystals down the plughole. Leave for a few minutes than follow them with boiling water.
