1 x RapidSterilise+

*Time may vary between 2-5 minutes, depending on the size of the feed.

How long do I need to wait to use RapidCool after sterilising it with RapidSterilise?

It depends on when RapidCool was last exposed to heat. If you’ve just made a bottle or washed it in hot water or the dishwasher, you’ll need to wait 3 hours after sterilising before using it again. But if your RapidCool has been cool for at least 3 hours, you can use it straight away after UV sterilising.
