Fast and good cleaning by dishwasher suitability

I love the dishwasher-safe Sprudlerflaschen for SodaStream. The exterior and particularly the threads and the lid are hygienically cleaned in the dishwasher, thereby catching less quickly to smell musty (if you, like my children drinkt directly from the bottle, that's a real problem). Even the interior of the bottle is quite good also cleaned. However, depending on the machine's (!), I clean basically every few days with additional Gebissreinigertabs the interior. The only minor drawback that I noticed is that when 1 of 4 bottles the ground has shifted slightly by the temperature in the dishwasher and it since has a slight imbalance, but no loss of volume. Also, my last bottles have held longer than the not dishwasher-safe bottle. This I had to throw away far before the expiry date, which are dishwasher-safe almost six months over it almost as were new.
