Instead of storing empty canning jars, fill them with water for use during an emergency until you need to use them.
Do I need to treat the water first ?
After thoroughly cleaning the mason jars, fill them with water.
All public water supplies are already treated and should be free of harmful bacteria.
However, as an added precaution, you can add 4-6 drops of chlorine bleach per gallon of water stored.
Mix this in a larger container then fill your mason jars.
This precaution protects you against any lingering organisms in storage containers that may have been inadvertently missed during the cleaning process.
No, you DO NOT have to do a water bath canning process to seal the lids.
Just place lid on top of mason jar and screw the ring on to hold in place.
