What You'll Learn
Identify the type of plastic
Identifying the type of plastic is crucial for understanding its properties, uses, and potential hazards. Here are some methods to help you determine the type of plastic you're dealing with:
Resin Identification Code (RIC)
The Resin Identification Code (RIC) system, introduced by the Society of the Plastics Industry in 1988, categorizes plastic resins into seven groups, each with distinct characteristics. These categories are widely accepted as a standard for classifying plastics worldwide. The RIC system is often used to facilitate recycling and can be found on product labels or packaging.
Visual and Tactile Inspection
Some types of plastic have unique visual and tactile characteristics that make them distinguishable. For instance, polystyrene is known for its brittleness and impact resistance, while polyvinyl chloride (PVC) products feel soft, tough, and sometimes sticky. PVC bottles often have a clear, streaky finish, and polystyrene foam is lightweight and buoyant.
Float Test
The float test is a simple method to determine the density of a plastic item. By placing the plastic in water, you can observe its buoyancy. Different types of plastics have varying densities, which can help rule out certain types. However, this test might not provide a definitive identification.
Burn Test
The burn test is another traditional method for identifying plastics. By burning a small piece of the plastic and observing the colour, smell, and behaviour of the flame, you can gain clues about the type of plastic. However, this test should be performed with caution and proper safety measures in place.
Product Information and Markings
Many products will have labels or markings that indicate the type of plastic they are made from. Look for symbols, abbreviations, or codes, such as "ABS" for acrylonitrile butadiene styrene or "PC" for polycarbonate. Manufacturers' websites can also be a source of information if the product itself does not provide sufficient details.
Laboratory Analysis
For a more precise identification, you can send a sample of the plastic to a laboratory for analysis. They have advanced equipment and techniques to determine the chemical composition and specific type of plastic. This method is especially useful when dealing with unknown or potentially hazardous materials.

Choose a suitable solvent
The first step in choosing a suitable solvent is to identify the type of plastic surface you are working with. Different types of plastic have different sensitivities to solvents. For instance, thinner polyethylene, polypropylene, acrylic, and fibreglass may be more resistant to stronger solvents. A simple way to tell these plastics apart is by melting an inconspicuous spot and observing the reaction. For example, polyethylene will drip and have a candle wax fragrance, while polypropylene will also drip but will have a dirty engine oil fragrance.
The next step is to identify the type of paint. Knowing the kind of paint you are trying to remove is crucial as this will determine the solvent you should use. For instance, water-based latex or acrylic paint can be removed with denatured alcohol or ammonia, while oil-based paints can be removed with paint thinner or mineral spirits.
It is important to note that some solvents can damage certain types of plastic. For example, acetone can melt many types of plastic, so it is recommended to start with low-impact solvents and move on to stronger ones if needed. Always do a patch test on an inconspicuous area to ensure that the solvent does not harm the plastic. If the plastic changes colour or texture, or indents when you press your fingernail into it, choose a different solvent.
Some solvents that can be used to remove UV paint from plastic include:
- Paint thinner
- Mineral spirits
- Lacquer thinner
- Citrus-based gel paint removers
- Eucalyptus oil
- Baking soda and water paste

Test the solvent on an inconspicuous area
When removing UV paint from plastic, it is important to test the solvent on an inconspicuous area first. This is because different types of plastics may react poorly to some solvents. To do this, put on some gloves and use a soft paintbrush or cotton swab to apply a small amount of the solvent to an inconspicuous area on the plastic item. Wait a few minutes, then rinse the solvent off. If the plastic changes colour or texture, or if it indents when you press your fingernail into the surface, choose a different solvent.
Some solvents may need hours before they have an adverse effect on the plastic, so it is important to be patient and observe the test area over time. If nothing happens to the plastic, the solvent may be safe to use. However, always wear gloves and a respirator mask to protect your skin and lungs from the chemicals.
It is also important to identify the type of plastic and paint before choosing a solvent. For example, thinner polyethylene, polypropylene, acrylic, and fibreglass may allow you to remove paint from their surfaces with stronger solvents. Water-based paints, such as latex or acrylic, can usually be removed with ammonia or denatured alcohol, while oil-based paints may require mineral spirits or paint thinner.
Additionally, some solvents may be more or less effective depending on whether the paint is still wet or has dried. If the paint is still wet, keep it wet by applying a paint thinner or even cooking oil until you can begin the removal process. If the paint has dried, you may need to use a heat gun, steam stripper, or infrared paint remover to soften the paint before scraping it off.

Apply the solvent and remove the paint
Before applying any solvent, it is important to test it on an inconspicuous area of the plastic item to ensure it does not damage the surface. Some solvents may need hours to show adverse effects, so be cautious and patient during this testing phase. If the plastic changes colour or texture, or indents when pressed, that solvent is not suitable. Always wear gloves and a respirator mask to protect yourself from the chemicals.
Once you have identified a suitable solvent, apply it to the paint you wish to remove. Use a natural bristle brush or a cotton swab to apply a small amount of the solvent to the painted area. Keep the solvent away from the plastic as much as possible, focusing on the paint itself. You can also place small items in a container with the solvent for one to three hours.
If the paint is still wet, keep it moist by applying a solvent like paint thinner or even cooking oil. This will prevent the paint from drying and make it easier to remove. Be careful not to use a cloth with too much dye, as it may leave a mark on the plastic.
For dried paint, you can use a tool to gently scrape off as much paint as possible without scratching the plastic surface. Choose a tool that won't cause scratches, such as a plastic scraper or your fingernail for curved surfaces. Hold the scraping tool at a slight angle and gently push it under the painted surface to lift the paint off.

Clean the surface with soapy water
To clean the surface with soapy water, you will need to prepare your work area first. Put on some protective gear, such as rubber gloves, and lay down a drop cloth in a well-ventilated area. This is important because some of the chemicals you will be using are toxic and require thorough hand-washing if you come into contact with them.
Next, you will need to identify the type of plastic surface you are working with. Different types of plastic require different care and certain solvents may react poorly with some plastics. To identify the plastic, you can use a match to melt an inconspicuous spot and observe the reaction. For example, polyethylene drips and has a candle wax fragrance, while polypropylene drips and has a dirty engine oil fragrance.
Once you have identified the type of plastic, you can start by soaking the area with warm, soapy water. Use some "elbow grease" to scrub the area and see if the paint comes off. If the paint does not come off, you can move on to other methods, such as using a paint scraper or paint thinner.
After you have removed the paint, you can clean the surface again with soapy water or a high-quality cleanser like Tri-Sodium Phosphate. Make sure to dry the surface completely afterward. You can also make a simple paste from baking soda and water and brush it on the plastic to remove any residual paint stains and debris from grooves and indentations.
