Soft plastics are notorious for becoming sticky over time. This phenomenon is caused by the breakdown of polymers in the plastic due to various factors such as heat, light, humidity, and natural oils from hands. The release of plasticizers, which are chemicals that make plastic more flexible, leads to the formation of a sticky residue on the surface. This issue is commonly observed in electronic devices, phone cases, remote controls, and children's toys, often requiring cleaning with appropriate solutions and prevention methods. Understanding the causes and exploring cleaning techniques can help address the sticky soft plastic problem.

What You'll Learn
Plastic coatings break down over time
Many plastic items, such as electronics, have a soft plastic coating that can break down and become sticky over time. This is due to the use of compounding additives like oils, antioxidants, and stabilizers by manufacturers, which can migrate to the surface and create a sticky feeling. Storing items in extreme temperatures can also accelerate this process.
To address this issue, the deteriorated coating must be cleaned off. While some have suggested using rubbing alcohol, this method has received mixed reviews. It is important to note that alcohol can remove the colour from certain types of coloured plastic, so it should be tested on an inconspicuous area first. Alternatively, a paste made from baking soda and water can be applied and then wiped off with a damp cloth. This method has been found to be effective in removing the sticky coating and restoring the plastic item to its original state.
Another option is to use a solvent like orange essential oil, which is effective in removing adhesive residue and can also be used to clean sticky plastic. However, this option may be more expensive. For delicate plastic items, a mild liquid dish soap and water solution can be used, applied with a soft cloth. This method is suitable for items such as plastic playing cards or credit cards, where there is a concern about damaging the colour or coating.
While it is possible to clean and restore sticky plastic items, prevention is also key. To slow down plasticizer migration, it is recommended to keep items at cooler temperatures as the migration occurs faster at higher temperatures. Additionally, avoiding soft-coated products can help prevent the issue altogether.

Heat and dust accumulation
Soft plastics can become sticky due to heat and dust accumulation. This is because soft-touch plastics have a coating that breaks down over time, resulting in a tacky surface that attracts dust. The accumulation of dust and the breakdown of the coating due to heat can cause the plastic to become sticky to the touch.
Soft-touch plastics are commonly used in electronics and other devices to provide a luxurious, rubbery feel. However, these coatings can deteriorate over time due to heat and dust, resulting in a sticky texture. This process is similar to "rubber reversion," where rubber products can become sticky again due to the breakdown of polymer crosslinks with time and heat.
To prevent soft plastics from becoming sticky, it is essential to store them in temperature-controlled environments and avoid extreme temperatures. Regular cleaning and maintenance of the plastic surfaces can also help remove dust and other residues that may contribute to the stickiness.
If soft plastic becomes sticky due to heat and dust accumulation, there are several cleaning methods to consider. One popular method is to use isopropyl alcohol, which can effectively remove the sticky coating. However, it is important to test the alcohol on a small, inconspicuous area first, as it may remove colour or affect certain types of plastic. Another option is to create a paste with baking soda and water, which can be gently scrubbed onto the plastic surface before being wiped off with a damp cloth.
Additionally, some people have found success using orange essential oil or orange oil-based products like Goo Gone to remove adhesive residues and smoothen the finish of soft plastics. It is important to note that the choice of cleaning solvent depends on the specific plastic item, and testing in a small area is recommended to avoid damage.

Storing in attics, basements, or garages
Soft plastics can become sticky due to the breakdown of their soft-touch coatings, which are designed to provide a luxurious feel to plastic surfaces when new. Storing items in attics, basements, or garages, which often experience extreme temperatures, can accelerate this process.
If you must store plastic items in these spaces, ensure they are stored in temperature-controlled conditions. Consider using a climate-controlled storage unit or an insulated storage area within your attic, basement, or garage. Maintaining stable temperatures can help prevent the breakdown of the soft-touch coatings and delay the stickiness from occurring.
Additionally, when storing plastic items in these areas, ensure they are kept in a clean and dust-free environment. Dust and dirt can accelerate the deterioration process and make the stickiness more noticeable. Use sealed containers or plastic bags to protect the items from dust accumulation.
If you are unable to control the temperature and humidity in these storage areas, consider using alternative storage locations, such as a climate-controlled self-storage unit or a temperature-regulated area within your home. By preventing extreme temperature fluctuations, you can help preserve the condition of your plastic items and slow down the stickiness from developing.
Remember, soft plastics are prone to becoming sticky over time due to the breakdown of their coatings. While proper storage conditions can help delay this process, it is a common issue that may eventually occur even with the best preventative measures. Regularly inspect your stored items and consider using the cleaning methods mentioned earlier if stickiness becomes a problem.

Ultraviolet radiation from sunlight
Soft plastic can become sticky due to deterioration over time, residue from hands, spills, or leftover adhesive from stickers or glue. To address this issue, various cleaning methods can be employed, such as using baking soda, isopropyl alcohol, water, or mild dish detergent.
Now, regarding ultraviolet radiation from sunlight:
Ultraviolet (UV) radiation is a form of non-ionizing radiation emitted by the sun and artificial sources like tanning beds. It plays a crucial role in producing vitamin D in our bodies. However, overexposure to UV radiation can lead to adverse health effects, including skin cancer, wrinkles, and premature aging. There are three primary types of UV radiation classified based on their wavelengths: ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). UVA rays cause skin wrinkling, tanning, and burning, while UVB rays damage the outermost layers of the skin, leading to sunspots, sunburns, and potential skin cancer development. UVC rays are mostly absorbed by the Earth's atmosphere, and their direct impact on Earth is minimal.
To protect yourself from the harmful effects of UV radiation, it is essential to practice sun safety. This includes seeking shade, wearing protective clothing, and using sunscreen with an SPF of 15 or higher. Additionally, it is recommended to limit exposure to the sun during the hours of 10 a.m. and 4 p.m., as almost half of the daily UV radiation is received during this period. The UV Index, which predicts UV radiation levels, can also be a helpful tool in planning outdoor activities and determining the necessary sun protection.
In summary, while some exposure to sunlight is necessary for vitamin D production, excessive UV radiation from the sun can have detrimental effects on our health. Therefore, taking precautionary measures to minimize overexposure to sunlight is crucial for maintaining overall well-being.

Humidity and mould
Mould can also contribute to the stickiness of soft plastics. Mould spores are present in the air and can land on surfaces, including soft plastics. When these spores find a damp environment, they can begin to grow and multiply, leading to mould growth on the plastic surface. This mould can cause the plastic to become sticky and tacky.
To prevent soft plastics from becoming sticky due to humidity and mould, it is essential to store them in dry and well-ventilated areas. Avoiding exposure to moisture and humidity can help maintain the integrity of the plastic material. Regular cleaning of soft plastics can also help remove any mould spores or accumulated dirt that may contribute to stickiness.
If soft plastics become sticky due to humidity or mould, there are several methods to clean and restore them. One common approach is to use isopropyl alcohol. Soaking a paper towel or cloth in isopropyl alcohol and rubbing it on the sticky plastic can help remove the sticky residue. However, it is important to test this method on a small area first, as alcohol can remove colour from certain types of coloured plastics.
Another effective method is to use a mixture of baking soda and water. By creating a paste and applying it to the sticky areas, the baking soda mixture can help lift the stickiness from the plastic. This method is especially useful for removing adhesive residue or built-up grime. After scrubbing the paste onto the plastic, it is important to wipe it off with a damp, soft cloth and then rinse the cloth and repeat as needed.
Additionally, orange oil or orange essential oil has been found to be effective in removing stickiness from soft plastics. A wipe-down with an orange oil-soaked rag can smoothen the finish and reduce tackiness. However, this option may be more expensive compared to other cleaning solutions.
