Plastic can be polished to restore its shine and there are several ways to do this at home. Polishing plastic is not difficult and can be done with basic household items such as white vinegar and water. You can also use baking soda, which you probably already have in your kitchen. For deeper scratches, you can use sandpaper, starting with the finest grit and working your way up. There are also specially formulated plastic polishing agents available on the market, such as Novus 2 scratch remover, which can be used with a buffing wheel attachment for drills.

What You'll Learn
Using a buffing wheel attachment
Buffing wheels are a great way to polish plastic at home, but it's important to be cautious as they can spin too fast and burn the plastic instead of polishing it. Before you begin, it's recommended to wear gloves as the wheel can get very hot. Start by using sandpaper, working down to a 1500-grit minimum. You can then move on to using a buffing wheel attachment.
There are various types of buffing wheels available, including cloth, cushion sewn, spiral sewn, sisal, muslin, and treated. It's important to choose the right type of wheel for the job, as using the wrong one can result in an uneven finish or even damage the plastic. For example, if you're working with cast polyester resin, a cotton cushion wheel is a good option.
When using a buffing wheel, always use light pressure and be careful not to apply too much pressure in one area, as this can cause the wheel to spin too fast and generate heat. It's also important to use the correct type of rouge for the job. Start with a harder wheel and a brown tripoli if the piece you're buffing needs heavy cutting. Remember to polish between steps and not to switch directly from one wheel or rouge to another without first hand-polishing the old rouge off.
Finally, always buy your polishing products from a reputable source to ensure quality and compatibility with plastic. It's also a good idea to practice on a small, inconspicuous area of the plastic first to ensure you're happy with the results and haven't caused any damage.

Polishing compounds
Jeweler's Rouge
Jeweler's rouge, or red polishing compound, is a popular choice for achieving a high-shine finish on various materials, including plastics. It is commonly used by professional jewellers to polish precious metals like silver and gold. This compound is ideal for the final stage of polishing soft, non-ferrous metals to a mirror finish. While it can be used on plastics, it may not be the best option for removing deep scratches or imperfections.
White Rouge
White rouge is another widely used buffing compound that can be applied to plastics. It is known for its fine abrasive properties and can deliver an ultra-smooth and shiny finish. White rouge is considered more aggressive than jeweler's rouge and is often used on harder materials like metals and wood. When using white rouge, it is important to start with a light touch and adjust as needed to avoid over-abrasion.
Blue Polishing Rouge
Blue polishing rouge, or blue plastic buffing compound, is specifically designed for finishing and restoring solid plastics and acrylic surfaces. It is ideal for edge finishing and providing a bright, reflective finish. Blue polishing rouge is a gentle compound that removes minimal material, so it works best on pre-prepped surfaces. It is a great option for achieving a clean, polished look on plastic items without removing too much plastic.
Pink Polishing Compound
Pink polishing compound is a vegetable-based, animal-product-free option that is safe for use on items that will come into contact with food or medical equipment. It provides a mild cut and high colouring, making it suitable for acrylics and plastics that have been prepared for polishing. This compound is a great choice if you are concerned about the safety and environmental impact of the products you use.
Black Buffing Compound
While black buffing compound is not recommended for use on plastics, it is worth mentioning as it is a common starting point for many polishing processes. This compound is ideal for removing surface imperfections and preparing materials for further polishing. It is often used on metals like steel, brass, and copper, but its aggressiveness makes it unsuitable for softer materials like plastics or precious metals.
When using any of these polishing compounds, it is important to follow safety precautions, such as wearing protective gear and ensuring proper ventilation. Additionally, always test the compound on a small, inconspicuous area of your plastic item before proceeding with the full polishing process to ensure satisfactory results.

Baking soda
Firstly, clean the plastic surface with a mild cleanser to remove dirt and debris. Mix a few drops of dishwashing soap in one cup of warm water and use a soft cloth or sponge to lightly scrub the plastic. This step is important as dirt and debris can scratch the plastic during the polishing process.
Next, prepare a paste by mixing baking soda and water. The ratio of baking soda to water should be 1:1, creating a thick paste. You can adjust the ratio slightly to achieve your desired consistency. Apply this paste to the plastic surface using a cotton ball, cloth, or clean toothbrush. Work the paste into the scratches with small, circular motions. Rinse off the paste occasionally to check your progress.
For deeper scratches, you may need to use a buffer. Buffing is particularly effective for harder plastics like acrylic and polycarbonate. Turn on the buffer and hold the plastic up to the buffing surface, allowing it to smooth out the scratch. You can also use a cotton buffing wheel or buffing wheel attachments for drills to remove scratches effectively.
Finally, rinse off the baking soda paste with water and dry the plastic surface with a clean, dry towel.

Vinegar and water
Once you have prepared the mixture, it is recommended to pour it into a spray bottle for easy application. Spray the solution onto the plastic surface in small sections, ensuring that you cover the entire area. After spraying, use a clean, dry, and soft cloth to gently wipe down and polish the plastic. Work in small circular motions, gently applying pressure to buff away scratches and dull areas.
For deeper scratches, you may need to start by using fine-grained sandpaper dampened with water to gently buff them out. Work slowly and increase the sandpaper grit incrementally if needed. Once the scratches are smoothed out, switch back to fine-grained sandpaper to create a smooth finish before applying the vinegar and water solution for polishing.
Regular cleanings with the vinegar and water mixture will help keep your plastic items looking polished, shiny, and new. It is important to note that you should avoid direct sunlight when polishing with vinegar and water, as UV light can discolor and weaken plastic. Store plastic items away from windows, and cover them if left in outdoor areas.

Sandpaper
If the scratches are not coming out, increase the sandpaper grit incrementally, starting with 440-grit sandpaper and going up from there. Harder plastics may require stronger sandpaper. For severe imperfections, start with a coarse grit of 120, then move to 220-grit, and proceed to finer grades. You can then follow with 320-grit, 400-grit, and 600-grit sandpaper.
After sanding, switch back to fine-grained sandpaper to smooth out the surface and create a nice finish. You can then move on to shining and polishing the plastic.
To prevent damage to the surrounding area, it is recommended to tape off the section of plastic that you will be working on. Painter's tape or masking tape is suitable for this purpose.

Frequently asked questions
There are several ways to polish plastic at home. You can use a plastic polishing compound, a buffing wheel attachment for a drill, baking soda, or a simple mixture of vinegar and water.
Novus 3-step plastic polish is a popular choice. You can also use Simichrome, which gives good results but leaves a film that needs to be cleaned off. Microgloss polishing compounds #5 and #1 are also effective.
Start by putting the roughest compound on a rag and rubbing it in a circular motion until the edges of the scratch are mostly gone. Wipe off the compound, then use the next roughest compound in a circular motion. Once the scratch is worn down, remove it with a rag and finish with the smoothest polisher.
Simply hold the buffing surface close to the plastic to remove scratches.
