I have replaced the liquid in my Reo (I went from Root Beer to Pear) and I am still tasting root beer. The juices were in two different bottles so that is not the issue. I rinsed out the device as well as the bottle cap and I blew out the tubing via the 510 connection. Any ideas on how to get rid of the root beer flavor that is still persisting in the reo? It even still smells like Root Beer...
