IKEA KORKEN jars: dishwasher-safe glass, hand-wash the rubber seal

IKEA lists the glass component of its 1L KORKEN jar as dishwasher-safe, but requires handwashing the natural-rubber gasket. Avoid sudden temperature changes when adding hot contents.

A clamp-top jar has more than one material. IKEA's care directions for KORKEN 1L (article 302.135.47) distinguish dishwasher-safe glass from the hand-wash-only gasket and warn against thermal shock. These care steps do not replace tested procedures for shelf-stable home canning.

Empty the jar and inspect the glass rim and metal clamp for cracks or damage. Do not use a damaged jar.
Carefully remove the rubber sealing ring according to the jar's construction; do not pull or stretch it excessively.
For this KORKEN model, wash the glass jar by hand or in the dishwasher as the official label permits. Confirm the care label on other sizes or older variants.
Hand-wash the natural-rubber gasket with mild soap and water, then rinse thoroughly. Do not put this gasket in the dishwasher.
Allow the glass and seal to dry completely before reassembly. Check replacement seals if the gasket becomes brittle, cracked or deformed.
Before filling with hot food, pre-warm the glass gradually with warm water to reduce thermal shock. Never plunge room-temperature glass into boiling water; IKEA specifies a maximum temperature change of 50°C.
