There are a few simple tricks that usually work even if you are not very strong. Try them in order and stop if the jar or glass looks like it might crack.
Improve your grip
- Dry the jar and your hands, then use a rubber glove, thick elastic band, or a piece of rough cloth around the lid to get more friction.
- Hold the jar close to your body for leverage and twist the lid slowly but firmly rather than in a quick jerk.
Break the seal gently
- Turn the jar upside down at a slight angle and give the bottom a firm slap with the palm of your hand a few times, then try opening again.
- Or, very carefully slide the tip of a spoon or butter knife under the edge of the lid and pry just enough to let a little air in until you hear a soft pop, then twist it off.
Use heat on the lid
- Run only the metal lid under hot tap water for 20–30 seconds, or stand the jar upside down in a bowl of hot (not boiling) water so the lid is covered.
- Dry the lid, then use a towel or glove for grip and twist; the warm lid expands slightly and often comes off more easily.
Add leverage (if still stuck)
- Wrap a strip of duct tape around the lid with a long “tail” sticking out, then hold the jar with one hand and pull the tape tail like a handle to help twist.
- If jars are a constant issue (e.g., arthritis), consider a simple jar-opening gadget that clamps the lid and gives you extra leverage.
If the jar chips, cracks, or the lid bends badly, stop using force and transfer the contents (if safe) rather than risking broken glass.
