Glass storage jars have different care needs for glass, rubber seal and metal clasp. This guide follows the official materials and care directions for the 1 L KORKEN sold in Korea (302.135.47). It is routine-cleaning advice, not a tested home-canning, sterilization or room-temperature food-preservation method.

1. Empty the jar and inspect it. Stop using it for food if the glass is chipped or cracked or the clasp is damaged. Avoid touching any sharp broken edges.
2. Open the clasp gently and check how the rubber seal is fitted. Do not bend the metal wire or force off a gasket that does not detach readily; follow the instructions for your exact jar model.
3. Hand-wash the natural-rubber gasket with lukewarm water and mild dish soap. IKEA specifically excludes the rubber gasket from dishwasher washing. Clean creases gently and rinse thoroughly.
4. The glass jar itself is dishwasher-safe according to the product label. For hand-washing use a soft sponge and avoid knocking the glass against hard utensils or other dishes.
5. Let the washed glass and seal dry thoroughly, inspect for residue and damage, and reassemble correctly. If the seal is worn or no longer fits, check the compatible replacement gasket for this product.
6. Protect the glass from sudden temperature changes. IKEA says to warm it with lukewarm water before hot filling or sterilization, never put room-temperature glass straight into boiling water, and stay within the stated maximum 50°C temperature difference. This cleaning guide is not a substitute for a validated home-preservation procedure.
