What You'll Learn
Using a hairdryer and two pieces of glass
Prepare the Materials
Firstly, gather your materials. You will need a hairdryer, two pieces of glass that are large enough to cover the warped plastic, and optionally, a diffuser for the hairdryer. It is important to ensure that the pieces of glass are clean and free of any dirt or debris.
Set Up the Workspace
Find a safe workspace where you can place the materials. It is recommended to work on a flat surface that can withstand heat, such as a heat-resistant mat or a countertop. Ensure that the area is well-ventilated to dissipate the heat from the hairdryer.
Position the Plastic
Place the warped plastic between the two pieces of glass. The glass should be larger than the plastic to ensure even heat distribution and to avoid any direct contact with the hairdryer. You can use a piece of wax paper between the plastic and the glass to protect the plastic further.
Apply Heat with the Hairdryer
Turn on the hairdryer and set it to a medium or low heat setting. Hold the hairdryer at a safe distance above the top piece of glass. Move the hairdryer in a slow, circular motion to evenly distribute the heat. If using a diffuser, attach it to the hairdryer to help spread the heat more evenly.
Monitor the Plastic
As you apply heat, keep a close eye on the plastic. You will notice that the plastic will start to soften and gradually flatten. Be careful not to overheat the plastic, as it can melt. Adjust the distance and heat setting of the hairdryer as needed to maintain control over the process.
Apply Pressure
Once the plastic has softened and started to flatten, turn off the hairdryer. Carefully remove the top piece of glass and set it aside. Place a heavy, flat object, such as a book or a pot filled with water, on top of the plastic to apply pressure and help it retain its flattened shape as it cools.
Allow Cooling
Leave the setup undisturbed for several hours to ensure the plastic cools completely and retains its new shape. Remove the weight and carefully separate the plastic from the glass. Your warped plastic should now be significantly improved or perfectly flat.
This method may take some time and patience, but it is a safe and effective way to reshape warped plastic without causing further damage. Always exercise caution when working with heat and take the necessary precautions to protect your workspace and yourself.

Oven method
To reshape a warped plastic using the oven method, you will need to proceed with caution to avoid damaging your plastic items further. Here is a step-by-step guide on how to do it:
Firstly, you need to prepare your plastic item for the oven. Start by giving it a good clean with a glass cleaner, and you can also use products like Novus 2, depending on how stained the plastic is. Then, lay out a layer of parchment paper on a flat, oven-safe surface, such as a pizza stone or a baking tray. Place your plastic item on top of the parchment paper.
Next, preheat your oven to a relatively low temperature. Around 150°C is a good starting point, as you don't want to risk melting your plastic. Once the oven is preheated, carefully place the tray with the plastic inside and monitor it closely.
Keep an eye on your plastic item, and when it starts to soften and become pliable, it's ready for reshaping. Remove it from the oven carefully, and quickly but carefully reshape it with your hands or a tool, such as a weight or another flat object, to achieve the desired shape.
Finally, allow the plastic to cool down gradually. You can place a flat item, such as a heavy book or another flat, weighted object, on top of the plastic to ensure it sets in the desired shape as it cools. Leave it untouched until it has completely cooled down and set in its new shape.
The oven method is a convenient way to reshape multiple plastic items at once, but it requires caution to avoid melting the plastic. Always work with low heat and monitor the process closely to achieve the best results.

Hot water and books
One method to reshape a warped plastic container is to use hot water and books. Here is a step-by-step guide:
Prepare the Materials
Firstly, gather the materials required: a large container or bathtub, hot water, two large books, and a plastic ziplock bag.
Prepare the Plastic
Place the warped plastic item inside the ziplock bag, ensuring it is fully enclosed and protected from direct contact with the water.
Soak in Hot Water
Fill the bathtub or large container with hot water. Immerse the ziplock bag with the plastic item inside, ensuring it is completely covered by the hot water. Leave it to soak for a period of time, the duration of which may depend on the severity of the warping and the type of plastic.
Apply Pressure with Books
After soaking, remove the ziplock bag from the water. Place it between the two large books, ensuring the warped area of the plastic is targeted. The weight of the books will help flatten and reshape the plastic.
Allow to Cool and Dry
Leave the plastic between the books until it has completely cooled and dried. This step is important to ensure the plastic retains its new shape. The duration may vary depending on the thickness of the plastic and the temperature of the room.
Alternative Methods
It is worth noting that other methods, such as using a hairdryer, heat gun, or oven, are also mentioned as ways to reshape warped plastic. These methods involve applying heat to the plastic and then using weight or pressure to reshape it. However, care must be taken to avoid melting the plastic with excessive heat.

Heat gun
Using a heat gun is a common method for reshaping warped plastic. It involves using a heat gun to soften the warped plastic and then placing it between two sheets of glass to make it stay flat. This method is quite safe as long as you don't overheat the plastic. It is also important to let the plastic cool for a long time, otherwise, it will warp again.
- Use a heat gun to soften the warped plastic. Be careful not to overheat the plastic as it can easily transition from "hot" to "melted and warped".
- Place the softened plastic between two sheets of glass. This will help to keep the plastic flat as it cools.
- Allow the plastic to cool slowly. This is a crucial step as cooling too quickly can cause the plastic to warp again. Leave the plastic between the glass sheets for at least an hour or longer.
- Remove the plastic from between the glass sheets once it has cooled completely. It should now be reshaped and flat.
It is important to note that the heat gun method can be risky and may not be suitable for all types of plastic. It is always recommended to practice on a small piece of discardable plastic first to get a feel for how the heat gun affects the material. Additionally, this method may not work for older plastics, especially those from the early 1960s and before.
An alternative to using a heat gun is to use a hairdryer, which can be more forgiving due to its slower heating process. Another option is the oven method, which involves placing the plastic in an oven set to a low temperature to soften it, and then flattening it with weight on top as it cools.

Cold water
To reshape a warped plastic container, you will first need to soften the plastic by heating it. One way to do this is to place the plastic in hot water for about a minute. You can then remove the plastic from the water and reshape it with your fingers. Once you are happy with the shape, dip the plastic into cold water for 30 to 45 seconds. This will cool the plastic and ensure it holds its new shape permanently.
Another method to reshape warped plastic is to use a hairdryer or heat gun. Place the warped plastic between two sheets of glass and heat it for around 5 minutes. Then, place a heavy book or another weighted, flat object on top and allow it to cool for several hours. This method may be preferable if you want to flatten a piece of plastic.
You can also use an oven to reshape warped plastic. Preheat the oven to a low temperature, around 150 degrees Fahrenheit. Place the plastic on a flat, ceramic surface, such as a pizza stone, and cover it with parchment paper to prevent abrasion. Put another heavy, flat object on top, like a cast-iron pan. Monitor the plastic in the oven until it becomes soft and pliable, which can take 20 to 30 minutes.
During the summer, you can use the heat of the sun to reshape warped plastic. Place the plastic between two sheets of glass and leave it in direct sunlight for several hours. Alternatively, you can place the plastic inside a hot car with the windows up, allowing the heat to soften it.
Whichever method you choose, always exercise caution when handling hot objects and be mindful of the potential for melting or distorting the plastic.
