Soft plastic surfaces can become sticky as they age. This happens due to the breakdown of compounding additives like oils, antioxidants, and stabilizers that manufacturers use to make plastics feel soft. The stickiness can also be caused by residue from hands, spills, or leftover adhesive from stickers or glue. To fix aged soft sticky plastic, you can try cleaning it with a solution of baking soda and water, isopropyl alcohol, or liquid dish detergent and water. It's important to test any cleaning solution on a small, inconspicuous area first to ensure it doesn't damage the plastic. Additionally, keeping your plastic items in a cool environment can slow down the deterioration process.

Clean with a baking soda paste
If you have aged soft sticky plastic that you want to clean with a baking soda paste, here is a step-by-step guide:
First, ensure you have the right equipment and ingredients. You will need baking soda, water, a small bowl or container for mixing, a soft cloth, and a clean rag or paper towels. It is also recommended to wear gloves and work in a well-ventilated area to avoid breathing in any fumes.
Next, prepare the baking soda paste. Start by adding some baking soda to your container. Then, slowly add water and stir the mixture until it forms a paste with a consistency similar to toothpaste. The amount of baking soda and water needed will depend on the size of the plastic item you are cleaning. As a general guide, use equal parts baking soda and water, or about one tablespoon of each for a small item.
Once your paste is ready, it's time to apply it to the sticky plastic. Using your fingertips, scoop a small amount of the paste and rub it onto the plastic surface using circular motions. Make sure to cover the entire surface area that needs cleaning. Avoid using anything abrasive, like a scouring pad, as this may scratch the plastic.
After applying the paste, let it sit for a while. This will allow the baking soda to work its magic and loosen the sticky residue. Depending on the severity of the stickiness, you may want to let the paste sit for up to 15 minutes.
Now it's time to remove the paste. Take your soft, damp cloth and gently wipe away the baking soda paste from the plastic surface. Be sure to wipe away all the residue, and use a toothpick or cotton swab to clean out any cracks or crevices if needed.
Finally, let the item air dry completely before using it again. Place it in a dry area with good airflow and leave it undisturbed until it is fully dry. If you cleaned the battery compartment of an electronic device, be sure to leave it open to air dry as well.
This method of using a baking soda paste has proven effective for many people in restoring their sticky plastic items, and with these steps, you can also achieve like-new results.

Use isopropyl alcohol
Isopropyl alcohol is a popular solvent for cleaning sticky plastic. It is a synthetic alcohol commonly found in products such as shaving cream and antiseptic. It is also used in industrial applications.
Isopropyl alcohol is an effective way to remove sticky residue from plastic items. It dissolves oils, kills viruses and bacteria, and evaporates without leaving any traces. It is safe to use on electronics because it is non-conductive. However, it is important to note that isopropyl alcohol is flammable and can be absorbed into the skin, so it is recommended to wear gloves when using it.
To use isopropyl alcohol to clean sticky plastic, start by holding a clean cloth in your dominant hand. Tip the bottle of isopropyl alcohol onto the cloth to dampen it, then quickly tip the bottle back to avoid soaking the cloth. If the plastic item has crevices or sensitive parts, such as a keyboard, ensure that the cloth is barely damp to avoid any liquid dripping into cracks.
Gently rub the sticky areas with the damp cloth, using a clean section of the cloth as needed. Be careful not to get isopropyl alcohol into any electronic areas, such as switches or small openings. If the item is very sticky, you may need to use a lot of force to remove the coating.
It is important to test isopropyl alcohol on a small, hidden area of the plastic item first, as it can remove the colour from certain types of coloured plastic. Additionally, avoid using toilet paper when cleaning with isopropyl alcohol, as it will disintegrate. Instead, use squares of cotton fabric, such as old cotton t-shirts.

Try orange oil
If you have aged soft sticky plastic that you want to fix, one method to try is using orange oil. Orange oil is a popular solvent for removing adhesive residue and can be effective at cleaning up sticky plastics.
To use orange oil to clean sticky plastic, follow these steps:
- Soak a rag or cloth in orange oil: Fold a clean rag or cloth into a square or rectangle that fits comfortably in your hand. Then, soak it with orange oil.
- Wipe down the sticky plastic: Use the orange oil-soaked rag or cloth to wipe down the sticky plastic surface. Apply firm, gentle pressure and use circular motions, paying special attention to the stickiest areas.
- Rinse the surface: After wiping down the plastic with orange oil, rinse the surface with water to remove any residual oil.
- Dry the surface: Use a soft, dry cloth to gently dry the cleaned plastic surface.
It is important to note that while orange oil can be effective, it may not work for all types of sticky plastic. Additionally, it may leave a strong citrus smell, and it can mar the surface of the plastic. Always test the orange oil on a small, inconspicuous area first to ensure it does not damage the plastic.
Other methods that can be effective in removing sticky residue from plastic include using isopropyl alcohol, baking soda and water paste, dish soap and baking soda, or commercial products like Goo Gone or Goop hand cleaner.

Wash with warm, soapy water
If your plastic item has no sensitive electronics, you can clean it with warm, soapy water. This method works well for delicate plastic items like plastic playing cards, ID or credit cards, or other plastic items that you are worried about damaging the colour or coating of.
To clean your sticky plastic item with warm, soapy water, start by making a solution of liquid dish detergent and water in a small container. Squirt 1 tablespoon of mild liquid dish soap into a small bowl, cup, or other container. Then, fill the container up with warm water and mix the solution together with a spoon until it is foamy.
Once you have your soapy water solution, dip the corner of a clean, soft cloth into the solution. Hold the cloth in your dominant hand with your index finger pointed straight out and a corner of the cloth wrapped around the tip of your finger. Dip the part of the cloth with your index finger inside it into the solution quickly and pull it out right away so the cloth doesn't get too soaked.
Next, scrub the solution onto the sticky plastic item using circular motions. Pay special attention to the areas where the item is most sticky. Continue scrubbing until you have covered the entire surface of the item.
Finally, use a clean, soft, damp cloth to wipe away any remaining soapy residue from the plastic item. Rinse out the cloth and repeat as needed until the item is completely clean. If your plastic item has batteries, be sure to open up and wipe out the battery compartment as well in case any water got inside.

Apply methylated spirits
Applying methylated spirits is an effective way to clean sticky plastic. It is a suitable method for removing rubber residue from plastic. Methylated spirits can be purchased from hardware stores or local supermarkets. In the US, denatured alcohol is a similar product, but it should be used with caution as it contains methanol, which can be harmful.
To apply methylated spirits to clean sticky plastic, you will need a clean, soft cloth. Fold the cloth into a square or rectangle that fits comfortably in your hand. Hold the cloth in your dominant hand with your index finger pointed straight out and a corner of the cloth wrapped around the tip. Pour a small amount of methylated spirits onto the cloth, being careful not to soak it. You can also pour the methylated spirits directly onto the plastic surface, but this may result in more waste and increase the chances of it coming into contact with your skin.
Rub the damp cloth over the sticky plastic surface using back and forth or circular motions. Re-apply the methylated spirits to the cloth as needed and continue rubbing until the sticky residue is removed. Be sure to scrub any particularly stubborn areas until the residue is gone.
It is important to note that methylated spirits can be damaging to plastic, so it is recommended to do a patch test on a small area first. Additionally, always wear rubber gloves and safety glasses when working with methylated spirits, as it can be harmful if absorbed through the skin or inhaled in large amounts. Ensure that you are working in a well-ventilated space to minimise the risk of inhaling fumes.

Frequently asked questions
There are several ways to fix aged soft sticky plastic. One way is to use a mixture of baking soda and water to form a paste, which you can then scrub onto the plastic surface. Another method is to use a solvent such as isopropyl alcohol or acetone, but be cautious as these can damage certain types of plastic.
Soft plastic can become sticky due to a process called plasticizer migration, where compounding additives like oils, antioxidants, and stabilizers come to the surface over time. Storing items in extreme temperatures can also accelerate this process.
Besides baking soda and water, some mild liquid dish soap and warm water can be used to clean sticky plastic. Orange essential oil is another option, although it may be more expensive.
Many objects with soft plastic coatings can become sticky over time, including remote controls, game controllers, car steering wheels, and electronic devices such as laptops and external DVD-ROM drives.
