Yes, you can put fizzy and sparkling drinks into Chilly's Bottles.
Chilly's Bottles will also keep your drinks fizzy due to the airtight lid. However, the time it will keep drinks cold will vary significantly depending on the drink.
We recommend a really thorough clean straight after use with hot soapy water. For further cleaning please use bicarbonate soda and water.
Please be careful when removing the lid if you have been storing fizzy drinks in your Chilly's Bottle. Pressure can build up inside the bottle and can cause the lid to 'pop' off. We recommend exercising a lot of caution and opening the cap with a firm grip, with your hand over the top.
