Cleaning straws is not particularly hard, but people sure do love to complicate it. In my research, I came across tips about using all sorts of stuff like dental floss, denture cleaner, an espresso machine, and more – all clever, and yet, so unnecessary. All you truly need is one good brush.

What You’ll Need

  • Hot water
  • Dish soap
  • A pipe cleaner or straw brush
  • Baking soda (optional)


1. Rinse the inside of the straw: If you can, rinse your straw as soon as you’re done using it, so stuff doesn’t harden in there. To do, cap the bottom end with your finger and place the top end under hot running water from the faucet. Then release and let the water run through; do this a few times. If you see something chunky in there (like bits from a smoothie), try plugging up the bottom hole, filling the straw with water and blowing through the opening at the top.

2. Scrub the straw: Add dish soap to your straw brush, then push it into your straw and scrub it vigorously. Repeat from both ends of the straw. Don’t forget to clean the openings and the outside of the straw.

3. Add baking soda: If you still suspect or see debris, add the scrubbing power of baking soda. Sprinkle some onto your bottle brush, then scrub from the top and bottom as before.

4. Rinse: When you’re done cleaning, run the straw under hot water for another minute to flush out any remaining soap or baking soda. You’re done!
