If you are ever going to drink from a hydro flask, it is important to clean it before you do so. This is because the inside of the flask can become dirty and cause the drink to taste sour. It is also important to make sure that all of the liquid has been removed from the flask. To do this, you will need a pot, a sponge, water and some soap.

  1. Pour some water into the pot and set it on medium heat.
  2. Add a sponge to the pot and let it soak in water for about 10 minutes.
  3. Once the sponge has soaked in water for a few minutes, use it to clean all of the inside of your hydro flask lid. Make sure that everything is dry before putting it back on top of your hydro flask!
