What You'll Learn
Use satin varnish or lacquer
If you want to prevent fingerprints on plastic, one option is to use satin varnish or lacquer. This can be especially useful for raw, unfinished plastic with a deeply textured surface, which tends to absorb the oil from fingerprints, making it look much darker.
A layer of satin varnish or lacquer can help to seal the plastic, creating a barrier that prevents fingerprints from being absorbed into the material. It will also give the surface a more uniform appearance, making any existing fingerprints less noticeable. Satin varnishes and lacquers are available in a range of finishes, from matte to high-gloss, so you can choose one that matches the desired look for your plastic item.
When choosing a satin varnish or lacquer, it is important to select a product that is specifically designed for use on plastic. Some products may not adhere properly to plastic surfaces or may affect the colour or texture of the plastic in undesirable ways. It is always a good idea to test the product on a small, inconspicuous area of the plastic first to ensure that it does not cause any discolouration or other unwanted effects.
There are a variety of application methods for satin varnish and lacquer, including brushing, spraying, or wiping with a cloth. Be sure to follow the manufacturer's instructions for the specific product you are using and work in a well-ventilated area to avoid inhaling fumes. Allow the varnish or lacquer to dry completely before handling the plastic item or exposing it to use.
Using satin varnish or lacquer can be an effective way to prevent fingerprints on plastic, but it may not be suitable for all items. For example, if the plastic is frequently handled or exposed to harsh conditions, the coating may wear off over time, requiring reapplication. In such cases, it may be more practical to use a removable protective film that can be replaced as needed.

Apply silicone oil spray
Applying a silicone oil spray is one method to prevent fingerprints on plastic. Silicone oil spray, also known as Back to Black, can be used to treat plastic and prevent fingerprints from appearing.
Firstly, it is important to note that you should always test any chemicals on a small piece of plastic first, to ensure that they do not damage or discolour the surface. Apply the silicone oil spray evenly across the plastic surface. You may need to use a cloth to wipe the spray onto the plastic, ensuring a thin, consistent layer.
Silicone oil spray can help to prevent fingerprints by creating a barrier between the plastic and your fingers. The oil will fill in any small crevices and create a smooth surface, which is less likely to pick up fingerprints. However, this method may not be ideal as the oil can smear with fingerprints over time and will need to be reapplied.
To maintain the effectiveness of the silicone oil treatment, it is important to wipe down the surface regularly with a duster or cloth. This will help to distribute the oil evenly and prevent it from creeping back out of crevices.
While silicone oil spray can be useful for preventing fingerprints on plastic, it may not be a long-term solution. The oil may need to be reapplied periodically, and the surface will need to be regularly wiped down to maintain its effectiveness.

Use a lint-free, soft cloth with rubbing alcohol
One way to prevent fingerprints on plastic is to use a lint-free, soft cloth with rubbing alcohol. This method is ideal for removing fingerprints from glossy surfaces without causing scratches. It is important to use a lint-free cloth, as lint can be left behind on the surface, defeating the purpose of cleaning it. Microfibre cloths are a good option for this reason. They are effective at cleaning without leaving lint or scratches.
When using a lint-free, soft cloth with rubbing alcohol, it is important to follow the correct procedure. First, pour the rubbing alcohol onto the cloth. The amount of rubbing alcohol dispensed depends on the size of the surface being cleaned. Be careful not to use too much, as this can result in dripping. Once the cloth is adequately damp, wipe down the plastic surface. Go over the surface gently and evenly, ensuring that all areas are covered.
It is worth noting that while rubbing alcohol is effective at removing fingerprints, it may not be suitable for all surfaces. For instance, it is not recommended for use on unknown surfaces, as it contains ammonia, which could potentially cause damage. In such cases, a diluted solution of cheap car windshield washer fluid and distilled water can be used as an alternative. This solution typically only contains alcohol, water, and colourant, making it a safer option for certain surfaces.
To maintain fingerprint-free plastic surfaces, regular cleaning is essential. Keeping a lint-free, soft cloth in a handy location, such as the glove compartment of a car, can help facilitate this. Additionally, wearing gloves can be a preventive measure to avoid leaving fingerprints on plastic surfaces.

Wear gloves
One of the most effective ways to prevent fingerprints on plastic is to wear gloves. This creates a barrier between your fingers and the plastic surface, preventing the transfer of oils and dirt that can leave marks and smudges.
There are various types of gloves that can be worn to prevent fingerprints on plastic. Latex gloves, for example, can be effective in blocking the transfer of oils from your fingers to the plastic. They are typically used in automotive detailing to handle glossy black plastic panels and switches. If you're looking for a more comfortable option, driving gloves are also available, offering a stylish and functional solution.
In certain situations, you might prefer a more discreet option. In these cases, thin, disposable gloves can be a good choice. These gloves are designed to be inconspicuous while still providing protection against fingerprints. They are commonly used in modelling, where leaving fingerprints on unfinished plastic sheets can be a concern. By wearing gloves during the modelling process, you can prevent fingerprints and maintain the desired finish.
Additionally, when handling sensitive equipment or devices with glossy surfaces, such as laptops or computer cases, wearing gloves can be beneficial. Microfiber gloves, similar to those used for cleaning camera lenses, can be ideal for this purpose. They prevent fingerprints while also reducing the risk of scratches that might otherwise occur when handling these delicate items.
Wearing gloves is a simple yet effective solution to prevent fingerprints on plastic. By choosing the appropriate type of glove for your specific needs, you can minimize the appearance of fingerprints and maintain the pristine condition of plastic surfaces. Whether it's latex gloves for automotive detailing, driving gloves for comfort, or microfiber gloves for electronics, gloves offer a practical way to keep plastic surfaces fingerprint-free.

Use a clear film
One of the most effective ways to prevent fingerprints on plastic is to use a clear film. This method involves applying a thin, transparent layer of protective material over the plastic surface. This creates a barrier that keeps the plastic underneath free from fingerprints and other marks.
There are several types of clear films available, including those made from polyurethane, polyethylene, and polyvinyl chloride (PVC). These films are typically applied using an adhesive, which bonds the film to the plastic surface. It is important to choose a film that is specifically designed for use on plastic, as other types of films may not adhere properly or could damage the surface.
When applying a clear film, it is important to follow the manufacturer's instructions carefully. In most cases, the plastic surface will need to be thoroughly cleaned and dried before the film is applied. Any dirt, dust, or oils on the surface can interfere with the adhesion of the film and cause bubbles or other imperfections.
Once the surface is prepared, the clear film can be carefully positioned and smoothed out to remove any air bubbles. A squeegee or similar tool can be helpful for this process. After the film has been applied, it is important to allow it to cure completely before using the plastic item.
Using a clear film to prevent fingerprints on plastic can be a great option for a variety of applications, including automotive detailing, electronics, and plastic modelling. It is a relatively simple and cost-effective solution that can provide long-lasting protection against fingerprints and other types of surface contamination.
