🛍️ Arm & Hammer Super Washing Soda The original since 1846, and still just one ingredient.

🌿 Material: 100% sodium carbonate, a mined mineral. It softens water, cuts grease, and boosts any detergent you pair it with.

🚫 No Nasties: No fragrance, no optical brighteners, no surfactants, no enzymes. Nothing but the mineral.

🤝 Better Together: We pair this with 20 Mule Team Borax and AspenClean Oxygen Bleach Powder. Washing soda softens the water and cuts grease, borax boosts cleaning and brightens, and the oxygen bleach lifts stains. Three mineral-based products, with no petroleum ingredients in the wash.

❤️ The Combination That Won Us Over: These three together are what turned a dingy white bra new again in one wash. That is the reason we started recommending them.

♻️ Low-Impact: Completely biodegradable, sustainably mined, and sold in a recyclable paperboard box.
