There are various methods to soften plastic, depending on the desired outcome. For instance, to soften plastic for moulding, one can use hot water, a stove, or a microwave. However, if plastic has become sticky due to solvent contact, one can use isopropanol, a solvent that does not dissolve common polymers, to remove the solvent from the plastic.

Use acetone to soften Plastic Wood wood filler
Wood filler is a mixture of glue and gypsum or sawdust, used to fill in small holes and cracks in wood. It is often nitrocellulose-based, which means it dries quickly and is easy to clean. However, this also means that it can dry out in the can before you get a chance to use it all. As long as the filler hasn't completely hardened, you can use acetone to soften it.
First, open the can of wood filler and pour just enough acetone to cover the top surface. Then, use a stick or a 1/4-inch dowel to poke several holes into the filler so that the acetone can run into them. Pour more acetone until it's approximately 1/4-inch deep on top of the filler. Close the lid tightly and wait for around 15 minutes. Finally, reopen the can and mix the softened filler with the dowel.
You can also use this method to thin the filler to a milkshake-like consistency. Be sure to read the can's contents to determine the makeup of the filler before thinning. Avoid breathing acetone fumes.
Note that if you are using DAP plastic wood filler, you can use equal parts acetone and alcohol to reconstitute the filler.

Add water to soften the top of the filler
Wood fillers are available in water-based and solvent-based options. Water-based fillers are known to have a crumbly texture, which can make rehydration difficult. They are typically made with cellulose or gypsum. On the other hand, solvent-based fillers are smoother and more durable. They can also withstand the elements better than water-based fillers.
Wood fillers contain a small amount of water or other liquid that keeps them soft and pliable. Atmospheric oxygen oxidizes the wood filler, causing it to harden. This happens when the filler is exposed to oxygen for extended periods, causing the moisture to evaporate and the filler to shrink and harden.
To soften the top of the filler, add water as necessary. You can also use acetone or nail polish remover, which will easily soften the filler. Mix the filler well using a 1/4-inch dowel and add water until the filler is softened enough to apply. If the filler becomes too thin, add a couple of drops of wood glue.

Use hot water to soften water-based wood filler
Water-based wood fillers can be softened with water. If your water-based wood filler has started to dry out, you can use hot water to soften it. Here is a step-by-step guide:
- Open the lid of the container and pour in hot water. You only need to add enough water to cover the top of the hardened wood filler.
- Mix the filler well using a 1/4-inch dowel or stick. You can create channels in the filler by poking the dowel into several spots, allowing the hot water to penetrate the filler more effectively.
- Add more hot water as necessary. Keep mixing and adding hot water until the filler reaches your desired consistency.
- If you accidentally add too much water and the filler becomes too thin, you can add a couple of drops of wood glue to thicken it. Mix the glue thoroughly with the dowel until it is well combined.
- Once your filler is softened, you can use it to fill in small holes and cracks in the wood.
Remember, if your wood filler has completely hardened to the point of being brittle, it may not be possible to soften it, even with hot water. This method is most effective when the filler has started to dry out but is not yet brittle. Always check the contents of the can to determine the filler makeup before attempting to thin or soften it.

Prevent wood filler from drying out with plastic wrap
Plastic wrap is an effective way to prevent wood filler from drying out. It helps to maintain the moisture content of the filler by trapping moisture and keeping the air out.
To use plastic wrap to prevent wood filler from drying out, place a piece of plastic wrap directly over the wood filler before sealing the container. This will create an airtight seal and keep the filler moist, pliable, and workable. You can also place plastic wrap under the lid of the container for added protection.
In addition to using plastic wrap, there are a few other things you can do to prevent wood filler from drying out. It is important to seal the container tightly after each use and store it in a cool area away from direct sunlight and heat sources. It is also recommended to control the humidity of the storage environment, ensuring it is stable and not too high or low.
For exposed wood filler, you can use plastic wrap to cover it, reducing its exposure to air. This is especially important as exposed wood filler dries quickly. You can also use a fan to gently circulate the air in the room, avoiding direct airflow onto the filler to prevent rapid moisture loss.
By following these tips and utilizing plastic wrap, you can effectively prevent wood filler from drying out and maintain its malleable state.

Use a hand mixer to soften filler
Wood filler is a handy product used to fill in gaps, cracks, and countersunk holes in wood. It is a mixture of glue and sawdust or gypsum. Sometimes, the filler dries out in the can, and it needs to be softened before use.
One way to soften wood filler is to use a hand mixer. First, open the can and pour in just enough acetone to cover the top of the filler. Acetone is a type of solvent that can be used to soften water-based and oil-based fillers. Poke a few holes in the filler with a 1/4-inch dowel to create channels for the acetone to penetrate. Add more acetone until the top of the filler is covered, then close the lid tightly and let it sit for about 15 minutes. Finally, reopen the can and use a hand mixer to mix the filler until it reaches the desired consistency.
Alternatively, you can use hot water to soften the filler. Add about two tablespoons of hot water to the container—boiled water works well if you don't have access to an "insta-hot" water filler. Use a paint stirrer, knife, or scrap piece of wood to scrape and stir the filler, mixing it with the water. Put the container in the microwave and heat it for about one minute, watching carefully to ensure it doesn't boil over. Once small bubbles start to form, remove it from the microwave and continue mixing with a hand mixer until you achieve the desired consistency.
If the filler becomes too thin during the softening process, you can add a few drops of wood glue and mix it thoroughly. Always be sure to mix your filler well, as insufficient mixing can lead to issues with consistency.
Using a hand mixer is an effective way to soften and mix wood filler, ensuring a smooth and homogeneous consistency. Whether you use acetone or hot water to soften the filler, the hand mixer will help you achieve the desired texture for your project.

Frequently asked questions
Softening plastic wire can be done by applying heat, but this must be done with caution as the plastic can easily melt and break. It is recommended to use a hair dryer or heat gun, controlling the temperature so that the plastic only softens and does not melt. This process should be done outside or in a well-ventilated area due to the emission of toxic gases.
One method for stripping wires is to use a razor blade, box cutter, or utility knife. Hold the blade steady and pull the wire through, using a plastic cooler as a table to keep the blade in place.
Hardened plastic insulation on wires can make them very difficult to cut through and strip. Freezing the wire will not work if it is a PE grade direct burial jacket, as it is designed to withstand the cold.
