Description
Baking soda (sodium bicarbonate) is a basic ingredient use for cleaning, hygiene and cooking. It's a must hate that can even be used for your health (stomac burns for example). Here we will present its uses in cleaning.
Dry cleaner powder
Sprinkle some baking soda on the object you wish to clean. Let a few minutes to activate and brush in circle to clean more deeply. Brush again and / or use a vacuum cleaner to eliminate the powder and dirt. The previous method also works great to eliminate bad smells (especially animal's urine smells on fabric). If the smell is persistent, you can dilute a bit of baking soda in water and spray the object so that the baking soda can work more deeply in the fibers without soaking in. You can also use a spray made with 1/3 of white vinegar and 2/3 water. Please DO NOT mix both preparation, otherwise you could dammage the object (heat reaction). To eliminate smell from a room on long term, you can put a small bowl of baking soda that you will stir from time to time to reactivate its deodorant power. You know it's time to change your baking soda batch when it doesn't bubble when you put a small drop of vinegar on it
