I wonder why it is not self-evident that the Soda Stream replacement bottles are dishwasher-safe? The 4 bottles of my 2 bubbler are more than expired but were all "Spüli" -tauglich. Why is this good standard abolished? I drink a lot of soda stream water, because only a small surplus carbonic prefer, but I do not feel like washing by hand. The care instructions from the manufacturer to include several lines. I'd like to change the system. Also "SodaStream 1041242490 dishwashers - suitable Sprudlerflaschen, 2 x 1 liter" is no longer available!
