Preliminary: A matching bottle brush makes on SodaStream - bottles perfect sense, since these must not be rinsed with hot, but only with warm water. If you then intend to take various syrupy additives, it is important to come up with the brush everywhere. When unpacking can be seen at the brush what in other bottle brush (cheap from the supermarket) is the weak point: looking up a piece of wire out, so you will never be able to clean the bottom of the bottle thoroughly. I therefore have long switched to bottle brushes with a round sponge, because the make itself thermos back blank (from the inside). Otherwise, the brush fits perfectly into the bottle and makes them nice and clean, but just not the floor. This is particularly annoying when you have no time to rinse the bottle and the same soda has dried down. For only water-drinkers, the brush is good - everyone else should also work with a sponge brush to get really clean bottles. (A little tip from Alfons Schubeck: thus the sponge is sterilized, occasionally wet for 2 minutes in the micro - Caution: hot!)
