HOW DO I CLEAN A Boundless CONCENTRATE POD?
Unscrew the cap, remove the cotton and soak the metal pod and lid in Isopropyl alcohol (ISO). The higher the percentage of alcohol in your ISO (look for 91% or above), the quicker it will evaporate and be ready.
Once it has soaked long enough and the alcohol has changed color, you are ready to wash it off with warm water and dry it. After it dries, replace the used cotton with fresh cotton or another medium and start using.
If the taste is bad, it probably still has some alcohol in it somewhere and needs to be thoroughly rinsed and dried.
