A reusable straw is a narrow tube that liquid passes through and that almost nobody can see inside, which is a specific hygiene problem.
Why It Matters
A straw carries sugary drinks, milk, coffee and smoothies, and residue clings to the inner wall where a sponge cannot reach.
Damp, dark and containing food residue is the environment biofilm and mould establish in. It is not visible from the end, and it survives a rinse and a dishwasher cycle.
The occasional viral photographs of split straws revealing what is inside are usually straws that were only ever rinsed.
Cleaning Properly
- A straw brush, which is the whole solution
- Pushed all the way through, both directions, with hot soapy water
- Immediately after use rather than at the end of the day
- Rinsed and stood upright to drain and dry
- Never stored damp in a sealed drawer or bag
Sets sold with a cleaning brush included, of the kind at vitever.net, are supplying the item that makes the straw usable rather than an accessory.
Dishwashers Are Not Enough
The important point. A dishwasher relies on water striking a surface, and the inside of a narrow tube receives almost none of that spray.
A straw can come out of a dishwasher looking clean and still have residue along its length. The brush is not optional.
The Materials
Stainless steel is durable, does not stain and conducts heat and cold, which is noticeable with hot drinks.
Glass lets you see the inside, which is a genuine hygiene advantage, and it can break. Borosilicate is the type to look for.
Silicone is soft and safest for children, and it holds odour and stains more readily. Bamboo absorbs and needs the most care.
Metal Straws and Safety
Worth stating. Rigid metal straws have caused serious injuries when people have fallen with one in their mouth, and there have been fatalities.
They are not suitable for young children, for anyone with mobility or balance difficulties, or for use while moving. Silicone or a silicone tip is the safer option in those cases.
Hot Drinks in Metal
Stainless steel conducts heat efficiently and a metal straw in a hot drink can burn a mouth.
Replace When Damaged
A scratched or corroded interior harbours residue and cannot be cleaned reliably.
Carry a Case
A used straw loose in a bag stays damp and picks up whatever is in there.
Let Them Dry Upright
Draining is what prevents most of this.
