After-Canning Jobs
Cooling
Glass jars
As soon as you take jars out of the canner, complete seals if necessary.
Cool jars top side up. Put them on a rack or folded cloth to cool. Keep them away from drafts. Don’t cover.
When jars are cool, take off screw bands. Do not force bands that stick: loosen by covering them with a hot damp cloth. Wash hands and store them in a dry place.
Tin cans
As soon as you take cans out of the canner, put them in cold water. Change water frequently for fast cooling. Remove cans from water while they are still warm so they will dry in the air. If you stack cans, stagger them to allow air circulation.
Checking Seals
Check containers for leaks when jars or cans are thoroughly cool.
