Re-using jam jar lids
The Food Standards Agency recommends against re-using jam jars for commercial purposes, but many people are happy to re-use glass jars if they are well washed and sterilised. However it’s not a good idea to re-use jam jar lids as even after thorough cleaning they could harbour bacteria which can not only spoil your food but also make you ill. There is also a risk that you won’t achieve a completely airtight seal with a re-used lid, which will again spoil the contents of the jar.
If you are using a clip top lid or something like a Kilner jar with a sealing disc, you should replace the rubber sealing ring or the disc, but otherwise wash, sterilise and re-use the jar in the usual way.

Glass jars can be re-used almost countless times and in many different ways and by using new lids every time you preserve, you can be sure that you are creating a good seal and a bacteria free environment to keep your goods at their best.
To re-use glass jars you should wash them in hot soapy water and rinse well before sterilising. The easiest way to sterilise jars is to run them through the dishwasher on a hot cycle. Alternatively you can place them in the oven on a baking sheet at 140C for about 15 minutes, or boil the jars in a large pan of water for 5-10 minutes.
