First time you should boil with any kind of vinegar in a pot for 5-10 min. Especially the first use then rinse with soap at kitchen sink and leave out to dry – need to dry thoroughly. (I put them in my dishwasher but probably not ideal to do that but seems fine). I don’t use a straw brush but you can find a baby bottle/sippie cup cleaning brush. Also they will stain if you use for dark colored smoothie like raspberry but fade over time.
