Paint thinner can be used to remove paint from plastic
Before using any solvent to remove paint from plastic, it is recommended to test it in an inconspicuous area first to ensure it won't damage the plastic. This is because some solvents can damage or melt certain types of plastic. For example, acetone, lacquer thinner, and alcohol can damage or soften most kinds of plastic.
If you want to remove paint from plastic without using paint thinner, there are alternative methods you can try. One method is to create a paste made of three parts baking soda and one part water. Apply this paste to the plastic and gently rub it with a damp sponge. For tougher stains, let the paste dry before wiping it off. Another option is to use a nonabrasive all-purpose cleaner to remove paint from plastic.
When removing paint from plastic, it is important to be cautious and follow safety precautions. Some solvents, like alcohol, are very flammable and can cause burns if they catch fire. It is also recommended to start with the least toxic options, such as olive oil, and gradually increase the strength of the solvents if needed.

Not all paint thinners are suitable for use on plastic
Paint thinner can be used on plastic, but caution must be exercised as not all paint thinners are suitable for this purpose. The wrong type of paint thinner can cause the plastic to become brittle, discoloured, or warped.
Mineral spirits, also known as paint thinner, are not suitable for ABS plastic, HDPE, and EPDM. Lacquer thinner is also not recommended for use on plastic as it can melt the surface. Linseed oil should be avoided when working with EPDM, rubber, and neoprene, and methyl (wood) alcohol will damage ABS plastic and polyurethane.
It is crucial to perform a spot test on a small, inconspicuous area of the plastic surface before proceeding with any paint thinner. This involves applying a small amount of the paint thinner to a clean cloth or cotton swab and observing the plastic for any changes in appearance or texture.
When choosing a paint thinner, look for products specifically designed for use on plastic. Acetone, for example, may damage some types of plastic, so caution is advised. Always read the label and follow the manufacturer's instructions to ensure the product is suitable for your specific plastic surface.
By taking the time to select the appropriate paint thinner and following the necessary precautions, you can effectively remove paint from plastic without causing damage.

Paint thinner can be stored in PET containers
Paint thinner, also known as mineral spirits, can be stored in PET containers. However, it is important to note that not all types of paint thinner can be stored in plastic containers. Lacquer thinner, for example, can easily dissolve many types of plastics and should only be stored in containers specifically made for solvents.
When choosing a container for paint thinner, it is important to consider the type of plastic. Some plastics, such as HDPE (High-Density Polyethylene), are suitable for storing paint thinner, while others, such as LDPE (Low-Density Polyethylene), may not be as suitable. This is because nonpolar hydrocarbons in paint thinner can slowly diffuse through the sides of LDPE bottles and escape.
It is also worth mentioning that paint thinner is flammable and should be stored in a fireproof cabinet. Additionally, it is always a good idea to use the best containers available and to label them properly to avoid any accidents or mishaps.
While PET containers are generally safe for storing paint thinner, it is always a good idea to check the recommendations and warnings on the product's packaging. Different brands and types of paint thinner may have specific storage instructions that should be followed to ensure safety and effectiveness.
In summary, paint thinner can be stored in PET containers, but it is important to consider the type of plastic, take appropriate safety precautions, and follow the specific instructions provided by the manufacturer.

Lacquer thinner is very flammable and can melt plastic
Lacquer thinner is a highly flammable substance that should not be used indoors. It is also toxic, and should not be used without fume extraction or a respirator. It can be used to AB enamels, but it dries too fast for some people. Lacquer thinner is not safe to use on plastic, as it will eat away at the material and dissolve it. It is not recommended to use it on acrylic, EPDM, rubber, neoprene, polypropylene, polyurethane, PVC, or silicone, as it will damage these materials.
Lacquer thinner contains toulene and acetone, the latter of which makes up 25% of the active ingredients. Acetone will dissolve styrene, which is present in some plastics. Even plastics that are specifically made for solvents may not be able to withstand lacquer thinner. Lacquer thinner can also cause warping in thin sheets of plastic due to the stress of solvent exposure.
Some of the plastics that are most resistant to lacquer thinner include PVC and polyester. Nylon is another option, but it expands and contracts with changes in atmospheric moisture, which can cause the lacquer surface to crack. Polycarbonate is not a good choice, as it is highly susceptible to melting when exposed to lacquer thinner.
If you are looking to remove paint from plastic, it is best to use a different substance, as lacquer thinner will likely damage the plastic.

Acetone can be used to remove paint from plastic but may damage some types
Acetone can be used to remove paint from plastic, but it may damage some types of plastic. It is important to note that acetone is a powerful solvent that can dissolve some types of plastic, so it should be used with caution. While it can effectively strip paint, it is essential to consider the type of plastic involved and take the necessary precautions to avoid potential damage.
Acetone is commonly used as a paint thinner and can be effective in removing paint from various surfaces, including plastic. However, it is crucial to determine whether the plastic item is safe to clean with acetone. Some plastics, such as acrylic, are not suitable for storing or being exposed to acetone. Therefore, it is recommended to test the acetone on a small, inconspicuous area of the plastic first to ensure it does not cause any harm.
If the plastic type is unknown or not recommended for use with acetone, alternative methods should be considered for paint removal. Options like Simple Green, Super Clean, or alcohol can be used instead. These alternatives are less likely to damage the plastic and are generally safer options. However, they may require more time and effort to remove the paint completely.
Additionally, when working with acetone, it is essential to prioritize safety. Acetone vapors can be harmful, so it is crucial to work in a well-ventilated area away from flames or hot surfaces. Wearing rubber gloves and protective gear is also recommended to avoid skin contact and inhalation of the vapors.
In summary, acetone can be used to remove paint from plastic, but it is essential to exercise caution and consider the type of plastic involved. Testing on a small area first and opting for alternative methods if necessary are recommended approaches. By taking the proper precautions, one can effectively remove paint from plastic while minimizing the risk of damage.
