11 ingredients. What each one is for.

Made in Australia. No added fragrance. Two enzymes.

  • Aqua

    Purified water, filtered to remove the minerals that spot glassware.

  • Sodium Laureth Sulfate

    Lifts grease off plates so water carries it away. Makes the suds.

  • Cocamidopropyl Betaine

    Helps dishes rinse clean rather than streaky.

  • Sodium Chloride

    Salt. Sets how thick the liquid is, so it pours in a controlled stream.

  • Sodium Formate

    Holds the pH steady across the shelf life.

  • Glycerin

    A humectant. Offsets the drying feeling of hot water on your hands.

  • Protease

    An enzyme that breaks down protein. Egg, cheese, milk film.

  • Lipase

    An enzyme that breaks down fats and oils. Greasy roasting tins.

  • Methylchloroisothiazolinone

    A preservative. Keeps the bottle stable for 12 months.

  • Methylisothiazolinone

    The other half of the preservative pair, always used with the one above.

  • Calcium Chloride

    Softens hard water so minerals in the tap do not blunt the clean.
