You can try draping a textured hand towel or a silicone trivet over the lid for better friction. You can also use a rubber cleaning glove or even try stretching a rubber band around the outside of the lid. All of these will give you a better grip on the lid, making it easier to twist off.

If you can’t loosen it using a rubber glove, turn on the hot water and let it run until it reaches its maximum temperature. Hold the lid under the water for about 30 seconds. Thankfully, you’re still wearing rubber gloves, so you don’t have to worry about getting scalded.
Why does hot water loosen lids?
Hot water helps to remove a metal lid from a glass jar by causing the metal lid to expand at a faster rate than the glass jar. This creates a gap between the metal lid and the glass jar, which eventually causes the lid to pop open.

How do you open a tight metal lid?
Add some heat
Applying heat to the lid will expand it slightly, releasing it from its tight grip. Methods of heating include running the lid under hot water or putting the jar, lid first, into a bowl of hot water for 30 seconds. You can also use a hairdryer.
Does heating a jar help open?

Do you use hot or cold water to open a jar?
hot water
Fill a bowl with hot water, either from the tap or by heating on the stove. You only need enough to cover the lid of the jar, not the entire jar.

How do you release a vacuum?
While holding the pan handle with one hand (use a pot holder), grasp the lid handle and pull upwards to release the lid. This will usually release the vacuum seal.
How do you open an airtight steel container?
