ARMEX™ is a brand of the Church & Dwight Co., Inc. makers of ARM & HAMMER™ products since 1846. Sodium bicarbonate (baking soda) abrasive blasting originated in 1984 during the restoration project of the Statue of Liberty with the assistance of Church & Dwight. Project engineers were searching for a replacement for sand blasting. Baking soda was the answer, with its extraordinary cleaning and coating-removal properties, all while not causing any damage to Lady Liberty’s delicate copper skin. At the completion of the project, over 200,000 pounds of ARM & HAMMER™ baking soda were used to abrasive-blast Lady Liberty. Following this success, Church & Dwight launched the ARMEX™ brand — the first sodium bicarbonate blasting abrasive — in 1989. Today, ARMEX™ has 12 task-specific formulations that can be used for both dry and wet blasting in contained cabinets or portable blast pots.
