Materials: Made of non-toxic food grade Stainless Steel. The electropolished interior doesn’t retain or impart any flavours no matter what liquid it is used for.
Cleaning: EcoStraws are dishwasher safe so all you have to do is rinse the straw and toss it inside the dishwasher and you are good to go. They also come with 2 cleaning brushes, to ensure that every inch of the straw remains spick and span. Do not use bleach or cleaners containing chlorine or abrasives on your Stainless Steel Straw.
