Setup, Compatibility & Care
To ensure a proper vacuum seal, always use a fresh metal sealing disc for each new canning project, as the compound on the rim is designed for single-use to maintain safety. Before filling, inspect the jar rim for any chips or cracks, as these will prevent the seal from forming. Clean the jars by hand with warm soapy water and rinse thoroughly; while the glass is dishwasher safe, the metal bands should be hand-washed and dried immediately to prevent rust. Store the jars in a cool, dark place once the seal is confirmed to maintain the color and quality of your preserved foods.
