How to clean the sink drain without detergents too aggressive for pipes and the environment? The key word is “salt” and the recipe is very simple: you have to dissolve a glass of salt in a liter of boiling water.

The salt reduces the accumulations of grease and removes bacteria that have found accommodation along the tubes. Pouring the mixture into the drain a couple of times a month, you can say goodbye to dirt and unpleasant smells.

Another tip: For a scented sink, use the orange or lemon peel! Their persistent fragrances defeat all the smells!
