In our bottles only still water comes and is washed with warm tap water. Since the bottles are in constant use, I simply times new drinking closures bought because the old has come already looked a bit ugly or something chewed and lost in a closure of the sealing ring. Unfortunately we had to say in the meantime that the sealing ring gives off a nauseating smell and taste of bottle and water. In haste, I wanted another drink * spit *, not the point, as if the contents toppled. The water was only a few hours in it. But all this comes from the rubber gasket, the new is white and old is beige. With the old sealing ring the water could drinstehen several days because no disgusting rumor / taste developed. Therefore not recommended. Please eight match.
