Our take on the Arm&Hammer Bicarbonate 50# CS

This is a 50 lb bag of Arm & Hammer baking soda, the same sodium bicarbonate sold in small boxes but in a bulk sack meant for refilling, cleaning and deodorizing in volume. It suits households that go through baking soda fast, plus cleaning, laundry and pool or septic maintenance. Against boxed baking soda it is the same product in a larger format, so the trade-off is storage and keeping it dry rather than any difference in what it does.

Questions and answers

Is this the same baking soda as the small boxes?
Yes. It is Arm & Hammer sodium bicarbonate, just packed in a 50 lb bag instead of a box.
Can I use it for baking?
It is food-grade baking soda, so it can be used in baking, but a 50 lb sack is impractical for most kitchens. Most buyers use it for cleaning and deodorizing.
How should I store it?
Keep it sealed in a dry place. Baking soda absorbs moisture and odors, so transfer portions to smaller airtight containers and keep the main bag closed.
Can I use it in a pool or septic system?
Baking soda is commonly used to raise alkalinity in pools and to support septic pH. Follow the dosing guidance for your pool or system rather than guessing.
Does it come with a scoop?
No scoop is included. Plan on using your own measuring cup or scoop and keeping it dry.
