Cleaning
The heavy cleaner baking soda wishes it was. Degreases, unsours laundry, and softens hard water. It will bite skin and etch aluminum.
- Shelf life
- Indefinite dry
- Container
- Sealed. It pulls water and can turn lumpy.
- Grade
- Laundry grade. Not baking soda — different chemical, stronger alkali.
What it does
- ▸Laundry booster in mineral-heavy water
- ▸Degreasing shop parts and oven racks
- ▸Water softening for wash water
Store
- ▸Labeled so it never goes into cookies. That is baking soda’s job.
Hazards
- ▸More alkaline than baking soda. Gloves. Eye rinse if splashed.
- ▸Not for aluminum wash basins.

Gear
Gloves · Goggles for heavy mixing
In the field
You can bake baking soda into washing soda (low oven, time, chemistry) — or just buy the bag and skip the science fair.
Arizona note
Hard water is the default here. This bag does more work in Glendale than it does in Seattle.
