Arm & Hammer Baking Soda Now Deodorizes For 30 Days Instead Of 3 Months

Reader Kirin says he’s suspicious of Arm & Hammer’s assertion that the same 1lb of baking soda will only deodorize for 30 days when it used to work for 3 months.

I try to preempt nasty smells in the refrigerator by buying one of those handy Fridge-N-Freezer baking soda boxes where you can simply tear off the sides and allow it to absorb odors. But in the past three months, it looks like marketing got a hold of the packaging, and suddenly baking soda only works for one month instead of three! Arm & Hammer say that they are “America’s #1 trusted baking soda brand,” but I’m not really feeling the trust anymore…

How very, very odd. Arm & Hammer says that their baking soda is 100% pure sodium bicarbonate, so we’re assuming they haven’t changed the recipe. They also haven’t updated their FAQ. It still recommends changing the box every 3 months.
