Plastic items can become sticky over time due to the breakdown of their soft plastic coating, accumulation of residue, spills, or leftover adhesive from stickers or glue. While it may seem like a lost cause, there are several simple methods to restore these sticky plastics to their former glory using common household ingredients such as baking soda, isopropyl alcohol, water, mild dish detergent, and even talcum powder. With a bit of elbow grease and the right technique, your sticky plastic items can feel like new again.

What You'll Learn
Use a paste made of baking soda and water
If your plastic items have become sticky, it may be due to a soft plastic coating that has deteriorated over the years, or residue from your hands, spills, or leftover adhesive. A simple paste made of baking soda and water can be used to clean sticky plastic.
First, mix equal parts baking soda and water in a small bowl or cup, stirring until it forms a paste. The amount of each ingredient depends on the size of the plastic item you wish to clean.
Next, scoop some of the paste onto your fingertips and rub it all over the item in circular motions. Make sure to cover the entire surface of the sticky item, adding more paste as needed. Avoid using anything abrasive like a scouring pad, as this could scratch the plastic.
Finally, wipe off the paste with a soft, damp cloth. Moisten the cloth under running water, then wring it out so it is not dripping. Your plastic item will now be clean and free of stickiness!

Wipe down with isopropyl alcohol
To stop plastic from being sticky, you can wipe it down with isopropyl alcohol. This method works well to clean off adhesive residue, such as that left behind by stickers or glue. It is also effective for removing old soft plastic coatings that have become sticky over time.
To do this, hold a cloth in your dominant hand and pour a small amount of isopropyl alcohol onto the middle of the cloth. You can also use rubbing alcohol, as it contains isopropyl alcohol. Be careful not to pour too much, as you don't want the cloth to become soaked. If you are cleaning a plastic item with crevices or sensitive parts, such as a keyboard, ensure that the cloth is just barely damp to avoid any alcohol dripping into the cracks.
Next, pick up the sticky plastic item and hold it firmly in your non-dominant hand. Begin to rub the cloth with alcohol all over the plastic surface, turning the item as needed to reach all sides. Scrub firmly in back-and-forth or circular motions, paying extra attention to the areas that are most sticky.
It is important to note that alcohol evaporates quickly, so you don't need to worry about drying the item off after cleaning. However, alcohol can remove the colour from certain types of coloured plastic, so be cautious when using this method. Additionally, if you are cleaning a plastic item with a screen, ensure that everything is completely dry before turning the device back on, and avoid getting large amounts of alcohol around the edges of the display.
Using isopropyl alcohol to wipe down sticky plastic is a straightforward and effective method to restore your plastic items to a smooth and unsticky state.

Use a citrus degreaser
If you're looking for a way to stop plastic from becoming sticky, one option is to use a citrus degreaser. This method was recommended by a user on Reddit who successfully removed the sticky layer from an old mouse using a citrus degreaser designed for cleaning bike chains. The user reported that this method worked better than rubbing alcohol, which left them feeling like they were simply "pushing" the stickiness off.
Citrus degreasers are particularly effective at breaking down oils and grease, making them ideal for removing sticky residue from plastic surfaces. They are also less likely to damage the plastic compared to other solvents, such as acetone, which can be too harsh and potentially melt the plastic.
To use a citrus degreaser, follow the instructions on the product label and ensure the area is well-ventilated. Apply the degreaser to a clean cloth and rub it onto the sticky plastic surface in a circular motion. Let it sit for a few minutes to allow the degreaser to break down the sticky residue. Finally, wipe away the residue with a damp cloth and dry the surface thoroughly.
It is important to test the citrus degreaser on a small, hidden area of the plastic first to ensure it does not cause any discolouration or damage. Always read the product instructions and take the necessary precautions when using any cleaning chemicals.
By following these steps and using a citrus degreaser, you can effectively remove stickiness from plastic surfaces and restore them to their original condition.

Try lighter fluid or naphtha
Lighter fluid, or light naphtha, is a potential solution for removing stickiness from plastic. It is a solvent that can be used to remove glue and other sticky substances from plastic surfaces. Before using lighter fluid on a plastic item, it is important to test it on a small, hidden area first to ensure that it does not damage the plastic. This is because, depending on the type of plastic and the plasticizers involved, some solvents can break down the plastic further and make it even stickier.
Lighter fluid is particularly effective for removing residual glue, such as that left behind by stickers or adhesive labels. It is also safe for use on certain delicate finishes, such as the nitrocellulose lacquer finish on vintage electric guitars. In addition, lighter fluid is useful for cleaning items with a similar coating to automotive clearcoat, such as pinball machines.
When using lighter fluid to clean sticky plastic, it is important to be cautious and avoid using it on items with sensitive electronics or screens. It is also recommended to avoid using solvents on items with a lot of nooks and crannies, as it can be difficult to apply the fluid evenly and effectively.
Overall, while lighter fluid or naphtha can be effective for removing stickiness from plastic, it is important to test it on a small area first and use it with caution to avoid potential damage to the plastic item.

Apply talcum powder
If you have an item made of sticky plastic, you can use talcum powder to remove the stickiness. This method is particularly useful for items with irregular sticky parts, such as a noise-cancelling headset.
First, powder the item with talcum powder. Then, scrape the powder off with your fingernails or a wire brush. If there is still some stickiness left, simply apply more talcum powder. Eventually, all the residue will rub off, leaving a smooth, unsticky surface.
This "dry" method is a good alternative to other methods that use water or other liquids, as it does not require the item to be dried afterwards.
