Does Dishwashing Liquid kill bacteria?Updated 4 hours ago
TL;DR: No. Dishwashing Liquid is a detergent that lifts grease and food soils so microbes rinse away. It's not antibacterial and makes no sanitising claims. If you need sanitising, use heat (dishwasher sanitise cycle or very hot water) or a food-safe sanitiser.

Does it kill bacteria?
⚠ No. It cleans, not disinfects.
Dishwashing Liquid uses surfactants and enzymes to loosen oils, proteins, and starches so you can rinse them, and the microbes living in that residue, down the drain.
✓ When you need sanitising
Use Dishwashing Tabs on a cycle with a final hot rinse (65 to 70 degrees or higher) or the dedicated sanitise option. For hand-washing, rinse in the hottest water your hands and items safely tolerate, then air-dry. For baby items, illness, or food-safety needs, use a food-safe sanitiser as directed by the manufacturer.
What are good washing-up habits?
✓ Routine
Scrape first, wash with detergent, rinse well, then let items air-dry. Change sponges and cloths frequently and wash cloths on a hot cycle.
⚠ Don't mix
Don't use Dishwashing Liquid in your dishwasher or with bleach, ammonia, or other chemicals.
Soak, don't scrub
Dishwashing Liquid is enzyme-powered. Fill the sink, soak your dishes, and let the formula lift grease and food soils for you.
