Learn how to sterilise jars and lids using two methods - by boiling and in the oven. Sterlising jars is an essential step when bottling and preserving jam, fruit, chutney, veggies and more. Making sure your jars and lids are 100% sterlised is a key step in the preserving process, as even seemingly clean jars can contribute to the growth of mould or bacteria if not properly sterlised.

Prepare jars and lids

Inspect both the jars and lids to ensure there are no chips or cracks in your jars and no dents or bends in your lids. While lids can be used more than once, it's best to use relatively new lids.
Wash jars and lids in hot, soapy water.
Method 1 - Boiling

Submerge jars and lids in a large pan of water, then bring to the boil. Boil for 10 minutes. Keep the jars and lids in the hot water until ready to use. Remove from hot water using a jar lifter, aka canning tongs.
Method 2 - In the oven

Rubber seals
If you're using Kilner-style jars that have a rubber seal, do not sterilise the seals in the oven. Boil the seals instead, as the dry heat from the oven can ruin the seals.
