A quick rinse can make a blender look clean while residue remains around the blade assembly, lid seal, gasket or shaft.
Why this matters
Food Standards Australia New Zealand describes an outbreak investigation in which a stick mixer used for breakfast smoothies was contaminated after it was not properly dismantled, cleaned and sanitised. Food debris allowed pathogens to persist and contaminate later batches.
After every use
- Unplug the machine before touching blades or removing parts.
- Follow the manufacturer’s disassembly instructions.
- Rinse away visible residue before it dries.
- Wash food-contact parts with warm water and detergent, reaching grooves, seals and the underside of the lid.
- Rinse away detergent and air dry fully.
- Wipe the motor base with a damp cloth; never immerse it.
Self-clean cycles have limits
Warm water and a drop of detergent can clean many jugs effectively, but this does not override the manual. Inspect the lid, seal and hard-to-reach areas. Replace cracked seals and scratched or damaged food-contact parts.
Cross-contamination
Take extra care after raw egg, unpasteurised ingredients, nut allergens or ingredients intended for a vulnerable person. Clean before sanitising; sanitiser does not work properly through food residue. Use a dishwasher only where the manufacturer says the parts are dishwasher-safe.

Home users should follow the appliance manual. Food businesses must also meet the food-safety requirements that apply to their operation.
