How do I clean it regularly?
✓ Three steps
Rinse the pump head and straw under warm water after each use to clear residue.
If clogged, flush warm water through the pump until it runs clear. For stubborn buildup, soak the head in warm water for a few minutes first.
Store upright in a cool, dry place between uses to prevent leaks and buildup.
✓ Good habits
A quick warm water rinse keeps the pump mechanism clear and Dishwashing Liquid flowing smoothly. Store upright between uses.
⚠ Avoid
Don't use harsh chemicals on the pump and don't force the pump head when pressing. Both can damage the mechanism and shorten the 3,000-press lifespan.
⚠ Signs of buildup
Slow dispense, inconsistent dose, or sticky pump action usually mean residue has dried inside. Flush warm water through the pump until clear, or soak the head briefly first if buildup is heavy.
