Our straws are made from whole bamboo stalks - nothing recompressed! This makes them easy to clean and maintain. A well-made bamboo straw is long-lasting, and cleaning is easy!rnrnAll you need is to rinse them out under the tap after everyday use or shake in a jar of warm soapy water if you like. Every month or so, you can boil a pot of vinegar water mix and soak the straws for a few mins if you want a super thorough clean! We use an electric kettle, so we just pour boiling water into a pan or pot and add a spoonful of vinegar for the soak. (Vinegar is optional!)rnrnrnEasy peasy, we told you so!rnrnrnImportant tips:rn1. Always let your bamboo straws dry fully. They dry very quickly!rn2. Dry them flat - not standing up - so that water does not collect at the bottom. rn3. Store your straws in a well-ventilated place, and never in air-tight containers or jars.
