Is this the same as baking powder?

No. It is pure sodium bicarbonate and needs an acid plus heat to leaven. Baking powder already contains an acid.

Can I use it for cleaning?

Yes. It works as a mild abrasive for sinks, tubs and pans and as a deodorizer for fridges and drains.

Yes, this product is labeled kosher and contains no added allergens.

How should I store it?

Keep the tub sealed in a dry cupboard. Moisture makes it clump and weakens its leavening power.

Is $12.97 a good price for 1 lb?

That is high for a single 1 lb tub. Compare the per-pound price at other stores before buying.

It lasts a long time but loses strength over time. Test a spoonful in vinegar; if it fizzes, it still works.

Our take on the Arm & Hammer Baking Soda

Arm & Hammer Baking Soda is pure sodium bicarbonate in a 1 lb shelf-stable tub. It is the standard pantry and household workhorse: leavening for baking, an abrasive cleaner, a deodorizer for fridges and drains, and a mild antacid when mixed with water. The 1 lb size is small, so heavy bakers and cleaners go through it fast. At $12.97 at The Home Depot as of November 7, 2026, it is priced well above what a single 1 lb tub usually costs; 3 stores list it new.
