Setup, Compatibility & Care
To prepare your Kilner jars for use, wash the glass jars and metal clips with warm, soapy water before the first use. Ensure all components are completely dry before filling them to prevent trapped moisture.
When preserving wet goods, ensure you leave adequate headspace to allow for the expansion of contents during the sealing process. For maintenance, check the orange rubber seals periodically; if the seal becomes brittle or cracked, replace it to maintain the airtight integrity of the jar. Avoid placing these jars in direct contact with extreme heat sources or sudden temperature changes to prevent glass cracking.
