How to open a stuck jar lid: simple methods that work

1. Get a better grip

• Dry your hands and the lid. Condensation from the fridge makes a lid slippery.
• Add friction. A rubber glove, a silicone pot holder, a wide rubber band around the lid, or a damp tea towel all help your hand grip instead of slide.
• Hold the jar low and steady, close to your body on a counter, and twist the lid with your whole hand rather than your fingertips.

2. Break the vacuum seal

• Tap the edge of the lid a few times on the counter, turning the jar as you go, then try again. This can loosen residue in the threads.
• Lift the edge gently with the tip of a spoon (not a knife) slid under the rim of a metal lid until you hear a small pop. That sound is air getting in, and the lid usually turns easily after it.

3. Use warm water

Run warm (not boiling) tap water over the lid only, for about 30 seconds, keeping the glass mostly out of the stream. Metal expands a little more than glass, and the warmth softens sticky residue. Dry the lid before you twist. Avoid sudden big temperature changes: glass straight from the fridge can crack under very hot water.

4. Add leverage

Leverage helps if you have less grip strength, for example with sore hands or arthritis. Clamp-style and under-cabinet jar openers grip the lid edge and let you turn with your arm instead of your fingers. Hold the jar firmly with your other hand so it doesn't spin.

Safety first

• Don't use knives, screwdrivers or hammers on a jar. A slip can cut you, and chipped glass can end up in food.
• Don't heat a sealed jar in the microwave or oven.
• If a lid is bulging, leaking, or spurts when it opens, don't eat the contents. That can be a sign of spoilage. When in doubt, throw it out.
• Clean sticky threads after use so the lid comes off easily next time.

The short version

Dry hands, add a rubber grip, tap the edge or gently lift it to break the seal, warm water if needed, then leverage. Most stuck lids give in by the second or third step.
