A:Hi! Great question!
There are three options:
1: Rinse is out in the bathroom sink if you can! (if you're comfortable with that)
2: My co-workers and I will drink water out of the straw if we had any other beverage in it (especially if the drink was sweet) if we don't have access...view more to a sink.
3: If you don't have either of those options, you can put it in your pouch dirty and then we recommend hand washing your straw holder once you're home to make sure everything stays clean.view less
