Getting a grip on a stuck plastic jar lid can be frustrating, but there are several simple methods to try. Firstly, try drying your hands thoroughly and running hot water over the lid to loosen it. If that doesn't work, try using a rubber pot holder, glove, or dish towel to get a better grip. You can also try tapping the lid forcefully with a wooden spoon to break the vacuum seal, or use a rubber gripper, strap wrench, or even an electric jar opener for more leverage. For a quick fix, some suggest freezing the jar and then running just the lid under hot water to take advantage of contraction and expansion.

What You'll Learn
Try using a rubber gripper, rubber pad, or rubber gloves to open the jar
If you're struggling to open a stuck plastic jar, one simple solution is to use a rubber gripper, rubber pad, or rubber gloves to enhance your grip and twisting leverage. These tools are particularly useful for those with weak hands or limited strength.
Rubber jar lid grippers, which resemble pliers, are a great option for tougher jobs. They are designed to provide extra leverage when twisting stubborn lids. Simply position the grips around the lid and twist the gripper. Rubber grippers are available in different sizes, so be sure to check which lid sizes they can accommodate.
Rubber pads are another effective option. These thin, flexible rubber disks are placed around the lid, providing a secure grip and moulding to the shape of the jar or bottle top. Rubber pads are versatile and can be used on small beverage bottles as well as larger lids. They are also durable and long-lasting. However, some users have found them to be a bit pricey.
If you don't have access to a rubber pad or gripper, a pair of rubber gloves can also increase friction and improve your grip. Latex dishwashing gloves can be used, but rubber gloves are more effective against plastic. Remember to dry your hands thoroughly before donning the gloves, as oily hands can cause slipping.
By utilising rubber grippers, pads, or gloves, you can safely and effectively open stuck plastic jars without resorting to potentially dangerous methods like banging the jar against surfaces or using knives to pry open the lid.

Use hot water to loosen the lid
If you're struggling to open a stuck plastic jar, one simple method is to use hot water to loosen the lid. This works because most materials expand at high temperatures and contract at low temperatures. Metals, being good conductors of heat, absorb thermal energy from hot water more easily than glass, which is a poor conductor of heat.
To use this method, start by running the lid under hot water for about a minute. You can also try placing the jar upside down in a bowl of hot water for 30 seconds. Alternatively, if you don't have access to a constant hot water source, you can fill a deep pan or dish with just-boiled water and then set the jar upside down in the hot water bath for about a minute.
As the metal lid absorbs heat, it will expand slightly, creating a gap between the lid and the jar. This expansion will release the lid from its tight grip, and you should be able to twist it off with a dry dish towel or potholder.
If the lid is particularly stubborn, you can try combining this method with a gripping device. For example, you could use rubber gloves, a rubber pad, or a jar-opening tool to enhance your grip and twist the lid off more easily.

Try freezing the jar to shrink the glass
If you have a stuck plastic jar, one method to open it is to try freezing the jar to shrink the glass. This method is particularly useful if the jar has a metal lid or is made of glass. Freezing the jar will cause the glass to contract and shrink, making it easier to open.
To do this, place the jar in your freezer for a few hours. The exact amount of time will depend on the size of the jar and the temperature of your freezer, but you should aim for at least a couple of hours. If you are in a hurry, you can place the jar in the freezer compartment of your refrigerator, which usually has a lower temperature than the main freezer.
Once the jar has been chilled, use a towel or oven gloves to protect your hands from the cold, and try to twist the lid off. The glass will have shrunk, and the lid should be easier to remove. If the lid is still stuck, try running the jar under warm water for a few seconds, or dipping the lid in warm water, as this will help to expand the glass and loosen the lid.
This method of freezing the jar is particularly useful for jars with metal lids, as metal contracts and expands more readily than plastic. It can also work for plastic lids, but the effect may be less noticeable. Combining freezing with warming the lid can be an effective way to loosen a stuck lid, as the contrasting temperatures will work to your advantage.

Use a strap wrench or oil filter wrench
If you have a strap wrench or an oil filter wrench in your toolbox, it can be very useful for opening a stuck plastic jar. These tools are designed to help you get a better grip and apply more force to the lid. They are especially useful if you have weak hands or a medical condition that makes it difficult to grip and twist objects.
A strap wrench is a simple device consisting of a rubber strap that tightens around the lid and a handle that you can use to apply torque. It works in a similar way to a pipe wrench, tightening like a stilsons grip. The rubber strap provides the necessary friction to grip the lid securely, allowing you to apply more force without slipping. This is especially useful for plastic lids, which can be difficult to grip due to their smooth surface.
To use a strap wrench, place the rubber strap around the lid of the jar, making sure it is centred and tight. Then, hold the jar securely with one hand and use the other hand to pull the handle of the wrench upwards and then over to the left. As you do this, the strap will tighten around the lid. Finally, simply turn the handle of the wrench to unscrew the lid. The wrench will transfer the force to the lid, breaking the seal and allowing you to open the jar with minimal effort.
An oil filter wrench is similar to a strap wrench but is specifically designed for removing oil filters from vehicles. However, it can also be very effective for opening stuck jars. Like a strap wrench, it has a rubber strap that tightens around the lid, providing the necessary grip and leverage to unscrew even the tightest lids. Oil filter wrenches are widely available and can often be found for less than $10, making them a cost-effective solution for opening stuck jars.

Try an electric jar opener
If you're struggling to open a stuck plastic jar, an electric jar opener could be a worthwhile investment. Electric jar openers are designed to apply the necessary grip to open even the tightest of jars. They are especially useful if you or someone you cook with has arthritis or lack the strength to open a jar manually.
You can keep the electric jar opener on a work surface, such as a counter or table, making it easily accessible when you need it. This gadget can save you time and effort in the kitchen and is perfect for those who have difficulty opening jars.
To use an electric jar opener, simply place the jar into the machine, ensuring the lid is properly secured. Then, press the start button, and the machine will grip and twist the lid, opening the jar for you. This process is quick and efficient, and you won't need to worry about finding other tools or making a mess.
Electric jar openers are available at major retailers, and while they may be considered a specialty item, they can be a valuable addition to your kitchen, especially if you frequently encounter stubborn jars.
