2. Setup and Installation
To use the Ball Regular Mouth Jar Storage Caps, ensure your glass preserving jar is clean and dry. These caps are specifically designed for regular mouth jars.
- Prepare the Jar: Ensure the rim of your regular mouth glass jar is clean and free from any food residue.
- Place the Cap: Position the plastic storage cap over the opening of the jar.
- Secure the Cap: Twist the cap clockwise until it is firmly sealed. Do not overtighten, as this is not necessary for a secure seal and could potentially damage the cap or jar.
These caps are compatible with both Ball and Kerr branded regular mouth jars.

3. Operating Instructions
Ball Regular Mouth Jar Storage Caps provide versatile storage options for various contents.
3.1. Refrigeration and Freezing
These caps are suitable for storing items in the refrigerator or freezer.
- Refrigerate: Use for freshly made sauces, fruit creations, make-ahead recipes, and opened preserved foods.
- Freeze: Use for freezer jams and other items intended for freezing. When freezing, it is recommended to use straight-sided jars labeled as freezer-safe to prevent jar breakage due to expansion.
3.2. Dry Storage
The caps are also effective for dry storage applications.
- Store: Ideal for dry pasta, layered mixes, dried herbs, and spices.
Note:
- Ball Plastic Storage Caps are not intended for processing during canning. For canning, use traditional two-piece metal lids and bands.
- For enhanced liquid-tight sealing, especially when storing liquids or for fermentation, some users place the flat metal disc from a traditional two-piece lid inside the plastic cap before screwing it onto the jar. This can provide an additional barrier.

4. Maintenance
These plastic storage caps are designed for reusability and easy cleaning.
- Cleaning: The caps are dishwasher safe. Place them on the top rack of your dishwasher for cleaning.
- Hand Washing: Alternatively, wash by hand with warm, soapy water and rinse thoroughly.
- Drying: Allow caps to air dry completely before storing to prevent moisture buildup.
- Reusability: With proper care, these caps can be reused multiple times, offering a durable storage solution.
5. Troubleshooting
5.1. Leaking
If a cap leaks, consider the following:
- Check Tightness: Ensure the cap is screwed on firmly.
- Jar Rim Condition: Inspect the rim of the glass jar for chips or irregularities that might prevent a proper seal.
- Add Metal Disc: For liquids or fermentation, placing a clean, flat metal canning disc inside the plastic cap before sealing can enhance the liquid-tight seal.
5.2. Odor Retention (for Fermentation)
When used for fermentation, plastic caps may sometimes retain odors.
- Dedicated Caps: Consider dedicating specific caps for fermentation use to avoid transferring odors to other food items.
- Soaking: Soaking caps in a vinegar solution or baking soda paste may help reduce persistent odors.
5.3. Rusting (Not Applicable to Plastic Caps)
Unlike traditional metal canning lids and rings, these plastic storage caps are rust-proof, eliminating concerns about rust contamination or degradation.
