Our PPSU bottles can be sterilised via the boiling, steam, ultra-violet ("UV") and sterilising tablet method.
For sterilisation by boiling: Bring the water to a boil, turn off the gas/induction, submerge components in the boiled water for no more than 5 minutes.
Do note that our PPSU bottles are able to withstand -20°C up to 180°C in temperature while PP and Silicone parts are able to withstand up to 110°C, please do remember to check that your steriliser does not exceed the aforementioned temperature range.
