A step-by-step routine for cleaning and storing your 650mL Demi bottle straws so they stay fresh, clear, and ready for daily use.

Quick answer

Rinse your Demi straws immediately after each use, wash them with warm water and mild soap using a straw brush, then air-dry them completely before storing them loosely in a clean, dry place.

Why silicone straws need a different routine

Silicone is flexible and gentle on your bottle, but it also holds onto moisture and flavors more than rigid plastic or metal. That means the two most important habits are thorough rinsing right after drinking and full drying before storage. Skipping either one is what leads to cloudy straws or a lingering taste.

The straws are designed to work with the Big/Demi Straw Cap, so you do not need to remove the cap to clean the straw itself. Keeping the cap and valve clean as part of the same routine prevents residue from building up where the straw meets the bottle.

When to replace rather than clean

Silicone can develop a permanent smell or a tacky surface over time, especially if it is stored damp. If a straw still smells after a full wash and dry, or if the surface feels sticky even when clean, replace it rather than trying stronger cleaning methods. The set of three makes it easy to rotate straws so one can dry fully while another is in use.

Step-by-step cleaning and storage

Rinse immediately after drinking: Run warm water through the straw as soon as you finish your drink. If you used a flavored or sugary beverage, rinse until the water runs clear. Do not let the straw sit with residue inside; dried residue is harder to remove and can leave a taste.
Wash with mild soap and a straw brush: Add a drop of mild dish soap to the straw, then push a straw brush through from end to end. Scrub the outside with your fingers or a soft cloth. Avoid abrasive brushes or scouring pads, which can scratch the silicone surface.
Rinse thoroughly inside and out: Hold the straw under warm running water and let water flow through the center. Rinse until no soap bubbles remain. Soap residue can leave a film and an off taste, so rinse longer than you think you need to.
Shake out excess water: Give the straw a few sharp shakes to remove as much water as possible, then gently flex it to release water trapped in any bends. Do not twist or stretch the straw aggressively; silicone can tear at stress points.
Air-dry completely: Stand the straws upright in a drying rack or lay them on a clean towel with both ends open to the air. Let them dry fully before storing. Never store a straw while it is still damp; trapped moisture is the main cause of musty smells.
Store loosely in a dry place: Keep dry straws in a clean, well-ventilated drawer or container. Do not seal them in an airtight bag while any moisture remains. A small mesh bag or open cup works better than a closed plastic container for everyday storage.
