Baking Soda Spray

Baking Soda

Ancient Egyptians used natural deposits of a Natron, which is a mixture of sodium carbonate and sodium bicarbonate, as a cleaning agent. Sodium bicarbonate is of course, baking soda.

Since then baking soda has been used for many applications such as cooking, as a fire control agent in dry chemical fire extinguishers (when you add heat to sodium bicarbonate it releases carbon dioxide), for many medical applications, personal hygiene , tons of other things and most importantly as a fungicide.

Common household baking soda helps cure and prevent powdery mildew by disrupting fungal spores the mildew uses to reproduce. It’s relatively inexpensive and safe to use mostly anywhere.
