Conclusion
There’s no way around the sterilization process, as it relates to cleaning the new canning jars and lids.
1. Clean the Canning Supplies
Run the jars and rings through the dishwasher. Put the canner or pot on the stove filled with water; let the water come to a boil. Use the tongs to put the jars in boiling water to sterilize them. Let the jars sit in the boiling water for 10 minutes (at altitudes lower than 1,000 feet), then remove them onto a clean dish towel.
2. Inspect the Rings
Inspect the canning rings to ensure none of them are bent or broken. Imperfectly fitting lids will not seal. Make certain all the rings and seals fit the size jars you have.
3. Fill the Jars
Fill the jars with the preserved item up to 1/2 inch from the top. Push a spatula or butter knife along the inside of the jar to release bubbles. Wipe the tops of the jars with a damp towel. Place the seal on top of the jar, then screw on the metal ring. Do not overtighten, but screw the ring on until it stops naturally.
4. Place Jars In Canner
Place the jars in the canner and turn on the heat. The water should cover at least 2 inches of the jars. Bring the water to a boil. Place the lid on top and boil for at least 10 minutes, up to 30 minutes. The time depends upon the type of preserved item. Follow the guidelines that come with the canning seals.
5. Remove Boiled Jars
Turn off the heat after the allotted time and remove the lid. Be careful of the steam. Use the tongs to remove the hot jars and place them on a dishtowel to cool. Allow them to cool overnight, then check the seals for bubbles. Label and date your canned goods and store them in a cool dark place.

What You Need to Reprocess Your Jars
Aside from your water bath canner (or pressure canner) and jars of food, the other canning supplies you'll need is just a fresh box of canning lids to complete the job. The lids are one-time use, and will not seal a second time.
How to Reprocess Unsealed Canning Jars
Follow these steps, and read through the tips, before trying to reprocess your jars. It may have been a fluke that your jars didn't seal the first time, but it's also possible that you accidentally skipped an important step. At any rate, it never hurts to refresh your memory.
Listen for the Ping
After removing jars from the canner, you should hear a 'ping' as each jar cools. This sound is a good indication that the jar has sealed properly.
Not Interested in Reprocessing Your Jars?
Just stick your jars in the refrigerator, or freeze the contents in freezer-safe containers. Unsealed jars aren't an indication that there's anything wrong with the food.
