Stuck plastic tubs can be a frustrating problem. The good news is that there are several methods you can use to separate them. One popular method involves using hot and cold water to your advantage. By filling the sink with hot water and placing the tubs in it, you can then add ice or cold water to the inside tub, causing it to contract, while the outside tub expands from the heat. You can also try using a blow dryer to apply hot air to the outside tub. Alternatively, you can try lubricating the seam with soapy water, vegetable oil, or baby oil to help the tubs slide apart more easily. If you're worried about making a mess, place the tubs in the sink or bathtub before attempting any of these methods.

What You'll Learn
Use hot and cold water
Using hot and cold water is an effective way to unstick two plastic tubs. This method works based on the principle of thermodynamics, where the hot water causes the outer tub to expand, while the cold water and ice cause the inner tub to contract, making it easier to separate the two.
To use this method, start by placing the nested tubs in a sink or a tub. If you're using a sink, make sure it's clean and dry before you begin. Then, fill the sink or tub with enough hot water to cover the bottom half of the outer container. Be careful not to scald yourself with the hot water. If you're using a tap, let the hot water run for a while to ensure it's at its hottest temperature.
Next, fill the inner container with cold water and ice cubes. You can use ice cubes from a freezer or simply add a few handfuls of ice to the inner tub. Make sure the cold water fills the inner container about halfway up the sides. The amount of ice and cold water you use will depend on the size of your containers, so adjust accordingly.
Let the containers sit in the hot and cold water for about 2-3 minutes. This will give the hot and cold temperatures time to work on the plastic, causing the desired expansion and contraction. After a few minutes, you can try gently pulling or twisting the containers apart. If they don't come apart easily, you can leave them in the water for a little longer or try some additional techniques, such as lubricating the rims with oil or dish soap to further reduce the friction between the containers.
Once you've successfully separated the tubs, it's important to clean them thoroughly. Wash the containers with mild dish soap and warm water to remove any oil or residue. Dry them with a clean cloth or leave them to air dry. Now you have your plastic tubs back, unstuck and ready for use!

Try a blow dryer
If you have two plastic tubs that are stuck together, one effective method to unstick them is to use a blow dryer. This method utilises the principle of thermodynamics, where the application of heat causes the plastic to expand.
Firstly, place the containers in a sink or bathtub, ensuring that they are secure and will not topple over. This step is important to avoid spilling hot water and causing potential burns. Then, fill the outer container with hot tap water, ensuring it covers at least half of the outside container. For the inner container, instead of using ice and cold water, you can use a blow dryer set to hot. Blow the hot air onto the inner tub, being careful not to get too close to the water in the outer tub.
The hot air from the blow dryer will cause the inner tub to expand due to the heat. Simultaneously, the outer tub will be expanding from the hot water. You may need to adjust the temperature and airflow settings on your blow dryer to find the optimal heat level. Additionally, ensure that you continuously blow hot air over the entire inner tub to ensure even expansion.
After a few minutes of applying hot air to the inner tub and allowing the outer tub to soak in hot water, you can try to gently pull the containers apart. If they do not come apart easily, continue applying hot air with the blow dryer for another minute or so and then try again. It is important to be gentle and not force the tubs apart, as this could lead to cracking or breaking the plastic.
This method is a safe and effective way to unstick two plastic tubs without causing damage. It is important to be cautious when handling hot water and to ensure that children or pets are not nearby to avoid any accidents.

Hit the seam
If your plastic tubs are stuck together, hitting the seam between them might help to get them unstuck. Here are some tips to help you do this effectively without damaging the tubs:
Firstly, place a towel underneath the tubs to reduce the risk of damage. You can then try carefully hitting the seam of the stuck tubs against a table corner or with your hand. This method works because hitting stuck objects can sometimes help to get them unstuck.
If hitting the seam does not work, you could try using a lubricant along the seam, such as soapy water or vegetable oil. Soak some paper towels in vegetable oil and place them around the perimeter along the seam. The oil will take time to work its way through the seam, but it will eventually help to unstick the tubs.
If you do not want to use oil, another option is to try the hot and cold method. Place the tubs in a sink or bathtub and cover the outside tub with hot tap water. Then, fill the inside tub with ice and cold water. Wait a few minutes before trying to pull the tubs apart. The inside tub will have contracted due to the cold, while the outside tub will have expanded from the heat, making it easier to separate the tubs.

Use lubrication
If you have two plastic tubs that are stuck together, lubrication can be an effective way to separate them. Here are some detailed steps to help you with the process:
First, place the nested tubs in a sink or a bathtub. This will help contain any spills and make cleanup easier. If the tubs are too large for your sink, you can also try placing them on a flat surface that can withstand hot water, such as a countertop or a table. Just be sure to protect the surface from potential water damage.
Next, you have a few lubrication options to choose from:
- Hot soapy water: Fill the sink or tub with enough hot water to cover about half of the outside container. Add some dish soap to the water and mix it well. You can also add a squirt of dish soap directly to the seam between the two tubs. The soapy water will act as a lubricant and help reduce friction between the tubs.
- Vegetable oil or baby oil: If you prefer to use oil as a lubricant, soak a paper towel in a light vegetable oil, such as canola oil, or use baby oil. Carefully roll up the paper towel and place it along the seam of the two tubs. The oil will slowly work its way into the seam, helping to lubricate the area and make separation easier.
While you're waiting for the lubricant to take effect, you can try some additional techniques to help loosen the tubs:
- Hit the seam gently: Carefully tap the stuck seam of the tubs against a table corner or with your hand. This impact can help dislodge the tubs and make them easier to separate.
- Use hot and cold temperatures: Fill the inside tub with ice cubes or cold water and then pour hot water over the outside tub. The cold will cause the inner tub to contract, while the hot water will cause the outer tub to expand, creating more space between the tubs and making them easier to pull apart.
Finally, after allowing the lubricant to work its way into the seam for a few minutes, it's time to try separating the tubs. Grip each tub firmly and pull them apart with a steady motion. If they're still difficult to separate, you can try using a tool, such as a butter knife or a flat-head screwdriver, to gently pry them apart. Be careful not to apply too much force, as you don't want to damage the plastic. With the right combination of lubrication and temperature manipulation, you should be able to successfully unstick your plastic tubs.

Cut connecting pieces
If the two plastic tubs are stuck together due to plastic connecting pieces, you can try to cut them using a knife or scissors. Be careful not to cut yourself or damage the tubs. If the connecting pieces are thick, you may need to use a saw to cut through them.
Another method is to try and snap the connecting pieces by pulling the tubs in opposite directions. This may require significant force, so be careful not to hurt yourself or damage the tubs.
You could also try to melt the plastic connecting pieces with a heat gun or blow torch. This will require careful application of heat to avoid damaging the tubs themselves.
If the tubs are stuck due to other reasons, such as suction or thermal expansion, then the above methods may not be suitable. In that case, you could try using a lubricating agent such as hot soapy water, vegetable oil, or baby oil. Soak a paper towel in the lubricating agent and place it between the tubs, allowing the agent to work its way into the seam. This may take some time, but it can help to slowly loosen the connection.
Another option is to use the temperature difference to your advantage. Place the tubs in a sink or bathtub, adding hot tap water to cover half of the outside container. Then, fill the inside container with ice and cold water. Wait for a few minutes before carefully trying to pull the tubs apart. The outer container will expand due to the heat, while the inner container will contract due to the cold, making it easier to separate them.
