SodaStream bottles are generally not recommended for use in the dishwasher. Most of the bottles, especially the plastic ones, are labeled as “hand wash only” by the manufacturer. High temperatures in dishwashers can potentially damage the bottle, weaken the material, or affect the seal, reducing its ability to safely hold carbonation.
However, some of the newer bottles, like those made from BPA-free plastic, might be more resistant to heat. It’s best to follow the specific care instructions provided by SodaStream for your bottle type. If you’re unsure, it’s safer to wash them by hand using mild soap and warm water.
