Arm & Hammer Super Washing Soda is a high-purity booster designed to increase the pH of wash water, which helps emulsify grease and heavy oils. This 55 oz box is a staple for "stripping" textiles or boosting the power of standard detergents in homes with very hard water. It is fragrance-free and phosphate-free, focusing purely on chemical lifting power.
The packaging consists of a high-density paperboard box. Because there is no internal plastic liner, the powder is susceptible to absorbing moisture from the air. Specifications suggest that in humid laundry rooms, the soda can harden into a block over several months; moving the powder to an airtight container after opening helps maintain its flowable texture.
Due to its high alkalinity, this product is very effective for household degreasing but can be hard on delicate fibers like silk or wool. Using gloves is recommended for those with sensitive skin when handling the powder directly or using it for manual cleaning tasks.
If you are looking for an all-in-one powder that already includes surfactants and enzymes for multipurpose cleaning, consider the Powerizer Complete Starter Kit.
