About this product
Three boxes of Super Washing Soda
This ARM & HAMMER Super Washing Soda offer contains three 55 oz boxes, totaling 165 oz by net weight. It is a powdered laundry booster and household cleaner, not a bottle of liquid detergent. Use it with regular laundry detergent according to the washing-soda directions. The manufacturer identifies the product as fragrance free, and the box lists sodium carbonate and water as ingredients. Despite the washing-soda name, it is not a food product and must not be consumed.
Measure for the wash or presoak method
For traditional or HE washing machines, the box directs adding half a cup with the regular detergent at the beginning of the wash cycle. Check colorfastness first and use the hottest water the garment permits. For a tough-stain or odor presoak, use two tablespoons per gallon of water for at least 30 minutes, with overnight soaking described for best results, then wash with half a cup and detergent. Do not use on leather, silk, wool or dry-clean-only garments.
Keep surface restrictions and precautions with the powder
For suitable kitchen and bathroom surfaces and appliances, dissolve half a cup in a gallon of warm water, wash the surface and rinse thoroughly while wearing rubber gloves. Do not use on aluminum, no-wax floors or treated wood. The powder and its solution can irritate eyes, and the product is harmful if swallowed. Avoid eye contact and prolonged skin contact, wear gloves and keep it out of children’s reach. Keep the boxes dry and retain the full directions for the particular task.

Questions about this product
Is the quantity 55 fluid ounces or three loads?
Each box contains 55 oz by net weight, and the selected pack supplies three boxes for 165 oz altogether. It is a powder. The pack count is not a wash-load count, and fluid ounces are not the unit used for the net contents of these boxes.
Does it replace my normal detergent?
The regular laundry method uses Super Washing Soda alongside the usual detergent. For a standard or HE machine, the box directs half a cup at the beginning of the wash cycle with that detergent. Follow the machine instructions and garment care labels when preparing and washing the load.
What changes for hard water?
The box’s water-softening directions specify one cup with the usual amount of detergent at the beginning of the wash cycle for hard-water conditions. That is a separate direction from the regular half-cup wash method. Check the complete package instructions before selecting the amount for your laundry.
How do I presoak suitable laundry?
Use two tablespoons per gallon of water and soak for at least 30 minutes; the label describes overnight soaking for best results. Then wash with half a cup of washing soda and detergent. Check colorfastness in a hidden area first, rinse the test area and let it dry before assessing it.
Which fabrics and surfaces should I avoid?
The laundry directions exclude leather, silk, wool and garments labeled dry clean only. The household-surface directions exclude aluminum, no-wax floors and treated wood. Follow those restrictions even when a stain looks difficult, and retain the item’s own care instructions rather than assuming every washable surface accepts the solution.
What handling and storage precautions apply?
The box warns that the product irritates eyes and is harmful if swallowed. Avoid powder or solution in eyes and prolonged skin contact, wear gloves and keep children away from the supply. Store the boxes dry and retain the complete label. It is a household cleaner and laundry booster, not food or baking soda.
