SodaStream FRESH bottle: dishwasher-safe body, handwash the plastic cap
SodaStream's FRESH 1 L plastic carbonating bottle is dishwasher-safe as labeled, but its plastic cap must be washed by hand. Its base can detach; confirm the bottle's model compatibility before carbonation.
Not every SodaStream carbonating bottle is dishwasher-safe. The FRESH 1 L product page allows dishwasher cleaning of the bottle but explicitly excludes black and white plastic caps. Other non-dishwasher-rated plastic bottles have stricter heat limits. Always check the specific bottle label and machine compatibility.
