Plastic pails can become stuck together due to changes in temperature, pressure, or humidity. This is a common problem, and there are several methods to separate them. One way is to use hot water, which can help expand the outer bucket and loosen the grip on the inner bucket. Another method is to use lubrication, such as soap or oil, to reduce friction and make it easier to pull the buckets apart. Drilling a small hole in the bottom bucket and using compressed air to create pressure between the buckets is also an effective technique. Additionally, it is important to avoid stacking dissimilar buckets, as they are more likely to become stuck together.

What You'll Learn
Using hot water
If your plastic pails are stuck together, one way to separate them is by using hot water. This method is especially useful if you do not have access to tools like an air compressor or a heat gun.
First, try to fill the inner pail with cold water or ice cubes. This will cause the inner pail to contract. Then, run the outer pail under hot water for approximately 30 seconds, or dunk it in a hot bathtub. The outer pail will expand, and the simultaneous expansion and contraction of the pails should make them easier to pull apart.
If you do not have access to cold water or ice cubes, simply using hot water on the outer pail may still be effective. The hot water will reduce the negative pressure between the pails and act as a lubricant, making it easier to pull them apart.
If the pails are still stuck, you can try using a combination of hot water and air pressure. First, drill a small hole in the bottom pail and fill the space between the pails with water. Then, stick an air nozzle against the hole and blast air into the crack. The water pressure and compressed air pressure will lift the top pail, allowing you to separate the pails without damaging them.
It is important to note that using hot water on plastic pails may cause the plastic to expand, making it more difficult to separate the pails. Additionally, some types of plastic may be more durable and resistant to hot water. Therefore, it is recommended to start with other methods, such as using compressed air or filling the pails with water, before resorting to hot water.

Drilling a hole
Firstly, identify where you want to drill the hole. A small hole near the top of the bucket can help relieve pressure. Alternatively, drilling a hole in the bottom of the bucket is also an option, as demonstrated by a user who successfully separated stuck buckets by drilling a 1/4" hole in the bottom bucket.
Next, gather your tools. You will need a drill and a drill bit that is appropriate for the material and thickness of your plastic pails. Choose a bit that is designed for drilling through plastic, as this will help ensure a clean hole and reduce the risk of the plastic melting or cracking.
Once you have your drill and bit, carefully create a hole in one of the pails. Take precautions to protect yourself, such as wearing safety goggles and gloves. If possible, clamp the pail in place to prevent it from moving while you drill. Start drilling slowly and increase speed as the bit penetrates the plastic. Apply firm, consistent pressure to ensure a clean cut.
After drilling the hole, you can try to separate the pails by pulling them apart. If they are still difficult to separate, you can use the hole to your advantage. One method is to fill the space between the pails with water and then use an air nozzle to blow air through the hole, as suggested by a user who had success with this approach. Alternatively, you can try spraying a small amount of lubricating oil through the hole, which may help the pails slide apart more easily.

Using a screwdriver
Firstly, it is important to identify the source of the problem. If the pails are stuck at the base, then prying them apart with a screwdriver may not be the best solution. In such cases, other methods like using hot water or filling one of the pails with water might be more effective.
However, if the problem is not at the base, then you can proceed with the screwdriver method. Start by warming up the outside pail with a heat lamp or hot water, as this will make the plastic expand and might help release the vacuum seal.
Next, take a flat-head screwdriver and carefully wedge it between the ridges of the pails. Gently pry the screwdriver handle to create a small gap between the pails. Be cautious not to apply too much force, as it may damage the plastic.
Once you have created a small opening, you can try to further separate the pails by using compressed air. Insert an air nozzle with a long tip into the gap and blow compressed air. This will create pressure and help push the pails apart. Alternatively, you can also use a hammer or mallet to gently tap on the screwdriver, creating a larger gap between the pails.
If the pails are still stuck, you can try combining methods. For example, after prying with the screwdriver, you can fill the inner bucket with ice water, causing the plastic to shrink and hopefully releasing the vacuum seal.
Remember to be patient and cautious throughout the process to avoid damaging the plastic pails.

Using compressed air
To use compressed air, you can follow these steps:
- Drill a small hole in the bottom of one of the pails. This hole will help release the vacuum by allowing air to enter the bottom pail.
- Acquire an air compressor with a nozzle or gun attachment. If you don't have access to an air compressor, you can use canned compressed air or even a pump typically used for inflating sports balls.
- Attach a rubber fitting to the air compressor to ensure a tight seal.
- Place the air compressor nozzle into the hole drilled in the bottom pail.
- Blast compressed air into the hole, forcing air between the pails. You can also direct the compressed air into the cracks between the pails if there is sufficient space.
- If the pails are filled with liquid, you can direct some of the compressed air into the liquid, allowing it to convert into gas and creating additional pressure.
- The compressed air will break the vacuum, and the pails should pop apart.
This method is a safe and efficient way to separate stuck plastic pails without resorting to more aggressive techniques that may damage the pails or require extensive cleanup.

Twisting and pulling
Using your hands and feet
Turn the buckets upside down so that the open end is facing toward the ground. Put your foot through the handle of the bucket that is closest to the ground. Grasp the rim of the top bucket and pull it up using your back muscles. You can also try to twist the top bucket while pulling. This method is more effective when the buckets are placed between your knees.
Using a screwdriver
If the buckets have handles, turn them upside down and step on the handle of the inner bucket. Grab the collar of the exterior bucket, twist, and pull. You can also try using a screwdriver to pry the lip of the bucket in several places, spraying a lubricant, and then pulling the buckets apart.
Using hot and cold water
Place the buckets in a bathtub or sink, depending on their size. Add enough hot tap water to the sink or tub to cover half of the outside container. Pour ice-cold water into the inside container until it fills halfway. Wait for two to three minutes and pull the containers apart. The inside container will have contracted due to the cold, and the outside container will have expanded from the heat, making it easier to separate them.
Using weights
Tie a brick or another large weight to the outermost bucket with a strong cord. Hang the innermost bucket up by the handle. Wait several minutes and then pull the stack of buckets apart. If this doesn't work, tie another weight to the other side and increase the amount of weight.
Using compressed air
Compressed air can be used to equalize the pressure between the buckets, making them easier to pull apart. You can use a high-pressure hose nozzle, an air compressor, or a can of compressed air with a straw to blow air between the buckets.

Frequently asked questions
There are several ways to separate plastic pails that are stuck together:
- Using hot water: The hot water expands the diameter of the outer bucket, causing a separation from the inner bucket.
- Using compressed air: Blowing compressed air down the sides of the pails can help release the vacuum.
- Using lubrication: Rinsing the pails with water and applying a little lubrication can help them come apart.
Here are some ways to prevent plastic pails from getting stuck together:
- Using spacers: Placing spacers such as clothespins or chunks of styrofoam insulation between the pails can prevent them from mating perfectly and sticking together.
- Buying pails from the same manufacturer: There is no standard size for plastic pails, so mixing different pails can cause them to wedge themselves together. Buying pails from the same manufacturer can help prevent this.
- Using paper or cloth: Placing paper or cloth down the sides of the pails can prevent a vacuum seal from forming.
Heavy-gauge plastic pails may require more force to separate. Here are some methods that can help:
- Using a screwdriver: Prying a screwdriver between the lips of the pails can help create airspace and release the vacuum.
- Using hot water and soap: Soaking the pails in hot water and soap may help to loosen the seal.
- Drilling a hole: Drilling a small hole in the bottom pail and blasting compressed air through it can help to release the vacuum and separate the pails.
