How To Sterilise Glass Bottles
Top tip! Before you start, make sure your bottles are able to withstand temperatures of up to 160c.
Start any of these processes by giving your bottles a scrub with soap and water first.
In The Oven
Heat your oven to 160c.
Line a baking tray with baking parchment and place your bottles on the tray.
Put in the oven for 15 minutes.
Remove from the oven and fill as soon as possible.
You can also use this method to sterilise glass jars and bottle caps or lids. If your lids are made of plastic, don’t put them in the oven unless you know they’re oven-safe. If you need an alternative method for your lids, you can boil them in water for 15 minutes.
When your bottles have been sterilised, it’s important that you fill and seal them as soon as you can to avoid any bacteria re-entering the bottle after the process is complete. However, safety is always first! Make sure you use oven gloves when handling your bottles and lids, and keeps kids and pets out of the kitchen until your bottles are safely sealed.
