Chapter 12
Household & Industry
Cleaning science, weed control, and historical industrial uses.
Cleaning & home
- Descaling: dissolves calcium carbonate in kettles, coffee makers, showerheads (5% works; patience helps).
- Glass and stainless cleaning, mineral-stain removal, deodorizing (neutralizes alkaline odors), fabric-softening rinse, rust soaking on tools.
Agriculture
- Weed control: household 5% burns tops only; 15–20% horticultural acetic acid is a genuine (and hazardous-to-handle) contact herbicide, regulated in places.
- Feed acidulant, silage aid, poultry-water sanitizer (regulated contexts).
Historical & industrial
Textile dyeing mordant; ink and pigment binder (historical); photographic stop bath; rubber latex coagulation; leather processing; eggshell calcium extraction; animal-hide preparation. Today’s bulk chemical acetic acid — vinyl acetate, solvents, terephthalic acid — comes from methanol carbonylation plants, not fermentation, and is a different supply chain entirely.
