How many times should I change my baking soda in the refrigerator? The answer is once a month to neutralize odors.
Here are a few ways to use baking soda:
freshen your mouth, use as a facial scrub, insect bites, polish silver and clean brushes and combs. For cleaning, try Arm & Hammer Baking Super Washing Soda as a laundry booster. I use it to wash my cleaning rags instead of bleach.
