For over 165 years, Arm & Hammer® Baking Soda has provided consumers with the cleaning and freshening secret that can be used in every room in your home. One of the most known uses for Baking Soda is deodorizing the fridge and freezer to keep foods taking fresher, longer.
Our recommendation to change the box of Arm & Hammer® Baking Soda in the refrigerator every 30-days is based on our continuing research efforts to understand the process of odor elimination and odor generation. In ARM & HAMMER's consumer research we found that people are not only concerned with the way their fridges or freezers smell but also with the way the foods taste after they've been in the refrigerator/freezer. For many years people used Baking Soda as a deodorizer, but by absorbing odor it also keeps food flavors from transferring to one another and therefore helps preserve the true flavors of foods. This is particularly important for milder tasting foods that are highly affected by food transfer such as ice cubes for which Baking Soda will help keep tasting like water instead of something else in the freezer. Our research has shown that 30 days is the optimal time to replace the ARM & HAMMER Baking Soda box for improved odor elimination, ensuring the fresh-tasting quality of food flavors are preserved.
