Sodium bicarbonate or soda (Na-HCO3) has multiple ecological qualities and is inexpensive. The variety and richness of its applications are astonishing. Baking soda can therefore replace many products that you pay so much for. Instead of buying anti-limescale products, chemical detergents, deodorizers and cleaning products... think about baking soda. Cleaning agent, softener, abrasive, pH regulator, deodorizer, anti-limescale... its applications are multiple!
