What's in Dishwashing Tabs?
✓ The 10 ingredients
Tap any ingredient below to see what it does for your wash.
Sodium percarbonate
Oxygen bleach. Releases hydrogen peroxide on contact with water to lift stains, brighten, and deodorise without chlorine.
TAED
Bleach activator. Lets the oxygen bleach work effectively at lower temperatures, so eco-cycles still get clean results.
Amylase
Enzyme. Breaks down starches from pasta, rice, potato, and sauces into water-soluble sugars that rinse away.
Protease
Enzyme. Breaks down protein-based food residue (egg, meat, dairy) into smaller fragments that wash off cleanly.
Sodium citrate
Water softener. Binds calcium and magnesium in hard water, preventing limescale and cloudy spotting on glass.
Sodium carbonate
Alkaline booster. Raises wash-water pH so grease and food residue break down faster.
Citric acid
Descaler. Dissolves mineral buildup on dishes and inside the dishwasher itself.
Sodium silicate
Corrosion inhibitor. Protects stainless steel, aluminium, and rubber seals inside the dishwasher.
Polycarboxylates
Dispersant. Keeps loosened food suspended in the wash water so it drains out instead of resettling on dishes.
Sodium sulfate
Stabiliser. Keeps the tab evenly mixed and dissolving cleanly through the wash cycle.
