Bicarbonate de soude

St Marc's 680 g pack of pure sodium bicarbonate (baking soda) is a food‑grade powder marketed under the name “Bicarbonate de soude.” It serves as a versatile leavening agent in baking and a natural deodoriser and mild abrasive for household cleaning tasks such as countertop wiping, fridge odor control, and stain removal. Although generally safe, the powder should be kept in a dry container to avoid clumping, and users should avoid prolonged inhalation and should not apply it to delicate surfaces like aluminum or natural stone.
