Welcome to ValorosoIT! Over time, the soft-touch coating on computers, dashboards, remote controls and other plastic objects often becomes sticky. In this article, we look at how to clean sticky plastic and remove deteriorated rubber coating using degreaser, alcohol and a microfiber sponge, with a few precautions to avoid damaging the surface.
I tried this method on my Dell Latitude E6230 laptop and on the interior plastic parts of my 1994 Fiat Coupé.

Why Plastic and Soft-Touch Coatings Become Sticky
Over time, some rubberized soft-touch coatings can deteriorate and become sticky. In these cases, the problem is not just dirt, but the surface coating itself deteriorating.
Anyone who has dealt with vintage items has probably encountered deteriorated, sticky rubber coatings. I experienced this with the interior plastic parts of my beloved 1994 Fiat Coupé and, more recently, with my Dell Latitude E6230 laptop. But don't worry: with a little patience and the right products, we can easily solve this annoying problem by removing the sticky rubber coating and exposing the plastic underneath.
Products Needed
Before getting into the details of the procedure, make sure you have the following products:
- A powerful degreaser, such as Chanteclair.
- 90% denatured ethyl alcohol (some people use isopropyl alcohol, but I have found that the alcohol commonly sold in supermarkets also gives excellent results).
- A non-scratch abrasive microfiber kitchen sponge with two sides: one soft and one more abrasive.
- Optional: a plastic restorer for car dashboards, for a glossy finish.
- Some cotton or microfiber cloths to gently dry the treated surfaces.
How to Clean Sticky Plastic and Remove Deteriorated Rubber Coating
Now that all the products are ready, we can start cleaning the deteriorated, sticky rubber coating. Follow these steps carefully for the best results.
- Preparation: first, make sure you unplug your computer from the power outlet and, if possible, remove the battery as well. Work in a well-ventilated area.
- Removing the Sticky Rubber Coating, Step 1: apply a generous layer of degreaser only to the areas affected by the deteriorated rubber coating. Make sure the product does not get inside the keyboard or computer. Using the abrasive microfiber sponge, gently scrub away the degraded rubber layer.
- Removing the Sticky Rubber Coating, Step 2: apply ethyl alcohol (or isopropyl alcohol) to the areas treated with degreaser to remove the melted, sticky rubber more effectively. Make sure the liquid does not get inside the computer.
- Repeat steps 1 and 2 until you achieve the desired result, removing all of the deteriorated sticky rubber coating.
- Rinsing and Drying: once the deteriorated rubber coating has been removed, wipe the surface with a cloth dampened with water to remove any alcohol and degreaser residue. Dry the surfaces thoroughly.
Advanced Options: Plastic Restorer and Repainting
Once you have removed the deteriorated rubber coating and cleaned the plastic underneath, you may want a finishing touch for a better appearance and additional protection. Here are two advanced options to consider:
- Applying a Plastic Restorer: if you want a glossy, protective finish, you can use a plastic restorer designed for car dashboards. These products are designed to revive treated plastic, darken its appearance and protect it from sunlight. Apply the product according to the manufacturer's instructions. After application, wipe the surface carefully with a microfiber cloth for an even, glossy finish. I chose this option for my Dell Latitude laptop.
- Repainting the Treated Parts: if you want a completely renewed and long-lasting appearance, you can repaint the treated parts. After thoroughly cleaning the surfaces, apply a primer suitable for plastic, followed by a coat of paint in the desired color. Apply a clear protective coat for greater durability and resistance over time. I chose this option for my Fiat Coupé. I recommend consulting specific tutorials on painting plastic, as it is not a simple job.
Precautions to Keep in Mind
Throughout the process, it is essential to take several precautions to avoid injury and damage to your computer:
- Work in a well-ventilated area because the chemicals are volatile and their fumes should not be inhaled.
- Do not let liquids get inside the computer, as they could cause irreparable damage.
- Be sure to protect the screen and other delicate plastic parts from the chemicals being used. Do not use degreaser or alcohol on areas where the rubber coating has not deteriorated.
- If you use a plastic restorer, apply it carefully and dry the treated surfaces thoroughly. Because the product can be somewhat slippery, be careful not to apply it where you normally hold the computer, as it could slip out of your hands.
