Old plastic action figures often become sticky due to plastic degradation. This is caused by the plasticizer, which is added to PVC to make it softer, vaporizing over time. The more plasticizer added to the PVC, the softer the PVC becomes and the more likely it is to sweat. This is a natural process, and all plastic action figures will eventually be affected by it. However, there are ways to slow down this process, such as storing the figures out of direct sunlight or artificial light, and using anti-UV screening or display cases. Additionally, owners can clean their figures with mild dish soap and warm water to remove the stickiness.

What You'll Learn
Plastic degradation is the cause of stickiness
If the figures are stored in sealed containers, the plastic cannot breathe, and the vaporized plasticizer clings to the figure, causing stickiness. This can be prevented by opening the figures' boxes and letting them breathe, as well as by storing them out of direct sunlight or artificial light, as this can accelerate the breakdown of the plastic. UV light and rays are particularly harmful, so anti-UV screening or display cases can help protect the figures.
To clean sticky figures, mild dish soap and lukewarm water can be used without damaging the paint. A soft-bristled toothbrush or cotton swabs can be used to scrub the figures, and if they remain sticky, they can be soaked in warmer, soapy water. This process may need to be repeated several times, and the stickiness may return, requiring further cleaning. It is important to note that figures with stickers will be damaged or removed by this cleaning process.

Soak in warm, soapy water to clean
So, your old plastic action figures have become sticky? This is a common issue with old plastic toys, and it's due to plastic degradation. Over time, the plasticizer—a substance added to PVC to make it softer—begins to vaporize and sweat, causing the stickiness. If your figures were stored in sealed containers, the vaporized plasticizer couldn't escape and ended up clinging to the figures.
To clean your sticky plastic action figures and restore them to their former glory, here's a step-by-step guide:
- Soak in Warm, Soapy Water: Fill a basin or container with warm water and add a mild dish soap or detergent. You can use products like Dawn dish detergent, which is known for brightening old toys. Submerge the action figures in the soapy water and let them soak. The duration of the soak may vary, but it often takes a few hours or even longer for heavily soiled figures. For figures with dust, a two-hour soak is recommended, followed by airing out for several weeks.
- Gently Hand Wash: After the initial soak, gently hand wash the figures. Avoid using sponges, brushes, or scrubbers, as these can damage the figures. Instead, use your hands to carefully clean the surfaces. Pay attention to crevices and joints, as dirt and grime tend to accumulate in those areas.
- Rinse and Repeat: After hand washing, rinse the figures with warm or cool water to remove any soap residue. If the figures still feel sticky, repeat the soaking and handwashing process as needed. Some figures may require multiple washes to completely remove the stickiness.
- Air Dry: After rinsing, gently dry the figures with a soft cloth. Avoid using tissues or paper towels, as these can leave lint on the figures. Allow the figures to air dry completely before handling them extensively or returning them to storage or display.
It's important to note that the stickiness may return over time, especially if the figures are stored in sealed containers. To prevent this, ensure your figures are stored in a well-ventilated area, and avoid direct sunlight or artificial light, as this can accelerate plastic degradation. Additionally, consider opening the containers periodically to let the figures breathe.
By following these steps, you can effectively clean your sticky plastic action figures and prolong their lifespan. Just remember to be gentle during the cleaning process to avoid damaging the figures' surfaces and paint.

Avoid direct sunlight to prevent stickiness
Old plastic action figures become sticky due to plastic degradation. Over time, the plasticizer used during manufacturing vaporizes, causing the plastic to sweat and become sticky. This is a natural process, and all plastic action figures will eventually be affected.
To prevent stickiness, it is important to avoid direct sunlight or artificial light, as this can accelerate the breakdown of plastic, leading to discolouration and bubbling. UV rays are particularly harmful, so anti-UV screening or display cases can offer protection.
Additionally, allowing figures to breathe by removing them from sealed containers or boxes can help prevent stickiness. Airing out the figures and providing ventilation can slow down the process of plasticizer vaporization and reduce the buildup of stickiness.
It is recommended to store or display figures in well-ventilated areas, away from direct sunlight or artificial light sources. This simple precaution can significantly prolong the life of the figures and maintain their original condition.
In summary, by avoiding direct sunlight, providing adequate ventilation, and protecting against UV rays, you can effectively prevent or slow down the stickiness that affects old plastic action figures. These measures demonstrate your care for your collection and ensure the longevity of your cherished items.

Use anti-UV screening for protection
Old plastic action figures can become sticky due to plastic degradation, which is often caused by exposure to UV light. This is known as photodegradation and can cause discolouration, loss of strength and flexibility, and make plastics brittle and prone to cracking.
To prevent this, you can use anti-UV screening for protection. There are several ways to increase a material's UV resistance and protect your plastic action figures:
Use UV-Resistant Plastics
UV-resistant plastics like PVDF, HDPE, and Polycarbonate are designed to withstand UV radiation and protect against photodegradation. These plastics are commonly used in outdoor applications and can be used to create protective cases or containers for your action figures.
Apply UV-Resistant Additives or Caps
You can increase the UV resistance of plastics by adding UV-resistant additives or caps. Carbon black, titanium dioxide, and benzotriazoles are common additives that act as blockers or absorbers of UV radiation, preventing damage to the plastic. These additives can be applied as a coating or integrated into the plastic during manufacturing.
Store Figures in a UV-Protected Environment
Keep your action figures away from direct sunlight or UV lamps. Store them in a cool, dry, and dark place, such as a closed cabinet or a box lined with UV-resistant fabric. Ensure the storage area is well-ventilated to prevent moisture build-up, which can also contribute to plastic degradation.
Regular Cleaning and Maintenance
Regularly clean your action figures with mild dish soap and lukewarm water to remove any dust, dirt, or oils that may accelerate degradation. Be gentle when cleaning, and avoid using abrasive tools that could damage the plastic. Proper maintenance will help extend the lifespan of your figures and slow down the effects of UV exposure.
By implementing these anti-UV screening methods, you can effectively protect your old plastic action figures from becoming sticky and prolong their lifespan.

Store in open containers to prevent stickiness
The stickiness on old plastic action figures is likely due to plastic degradation. Over time, the plasticizer used in manufacturing vaporizes, causing the plastic to sweat and become sticky. This is a natural process, and all figures will eventually be affected, but storing them in sealed containers accelerates the process by preventing the vaporized plasticizer from escaping.
To prevent this, store your figures in open containers that allow them to breathe and the plasticizer to evaporate. Avoid sealed containers, baggies, boxes, or any storage that doesn't allow for airflow. Keeping them in open storage will also help prevent discolouration and bubbling caused by exposure to direct sunlight or artificial light. Anti-UV screening or display cases can also help protect your figures from UV damage.
If your figures are already sticky, you can try washing them with mild dish soap and lukewarm water, being careful not to damage the paint. Soak a soft-bristled toothbrush or cotton swab in the soapy water and gently clean the affected areas. If the figure is very sticky, you may need to soak it in warmer, soapy water for a while before rinsing and drying it with a soft cloth. Be cautious when cleaning figures with stickers, as these may be damaged or removed during the cleaning process.
In some cases, the stickiness may persist despite your best cleaning efforts. If this happens, repeat the washing process as many times as necessary. The stickiness should eventually diminish, but it may return, requiring further cleaning.
