Dremel tools are versatile and can be used to polish plastic. To get started, you will need to choose the right polishing accessory for your project, such as a polishing cloth, wheel, or pointed cone. It is recommended to use a polishing compound to remove small imperfections and dull oxidized film. However, the red polishing compound that comes with the Dremel tool is too aggressive for clear plastic and should be substituted with a diamond spray, paste, or dry powder. Start polishing at 5000 RPM and stay below 15,000 RPM for the best results. Before using a Dremel tool, ensure that the plastic surface is smooth and clean.

Use a nylon brush to remove dust and debris from plastic without scratching
To polish plastic with a Dremel, it is important to start with the right tools and techniques to ensure the plastic surface is not damaged. One of the recommended tools is a nylon brush, which is ideal for removing dust and debris from a range of surfaces, including plastic, without causing scratches. Nylon brushes are designed with flexible bristles that expand during rotation, making them perfect for cleaning tight spaces and hard-to-reach spots.
When using a nylon brush with your Dremel, it is important to follow the correct procedure. First, ensure that the plastic surface is smooth and clean. This will help the brush effectively lift away any dust or debris. Then, select the appropriate RPM setting on your Dremel. For a soft polish, start at 5,000 RPM and slowly increase if needed, but stay below 15,000 RPM for the best results.
As you work, be gentle and avoid applying excessive force or pressure. The nylon brush, when paired with the rotating action of the Dremel, will effectively remove dust and debris without requiring a lot of pressure. Putting too much pressure on the tool can be counterproductive and may risk damaging the plastic surface.
Additionally, consider using a polishing compound with your nylon brush. This solid paste can be used sparingly in combination with the nylon brush to enhance the cleaning process. Simply hold the brush in the compound while it rotates until the compound is evenly spread. Then, you can start polishing the plastic surface, remembering to use the recommended RPM and replace your brush when necessary.

Start at 5,000 RPM for a soft polish, increasing slowly up to 15,000 RPM for best results
To achieve a soft polish on plastic with a Dremel tool, it is recommended to start at 5,000 RPM. This slower speed will help prevent heat buildup, which can cause optical distortion when polishing plastic. Even at low speeds, Dremels rotate thousands of times per minute, so heat can quickly become an issue.
Starting at 5,000 RPM allows for a gentle and controlled approach to polishing plastic. It is important to gradually increase the speed to achieve the desired finish. By slowly turning up the RPM, you can carefully monitor the process and make adjustments as needed. This methodical approach ensures that you do not apply too much pressure or cause any damage to the plastic surface.
As you slowly increase the RPM, you can begin to work on removing scratches and creating a smoother surface. It is recommended to stay below 15,000 RPM for the best results. Maintaining a speed below this threshold will help you achieve a high-quality polish without risking overheating or applying excessive force.
By following these guidelines and staying within the recommended RPM range, you can effectively polish plastic with your Dremel tool. Remember to use the appropriate accessories, such as nylon brushes or polishing wheels, and consider using a polishing compound to enhance the shine and remove imperfections. With patience and a careful approach, you can achieve a professional-looking finish on your plastic polishing project.

Use a diamond spray for high-level polishing of plastic
Diamond sprays are an excellent alternative to diamond suspensions for polishing plastics with a Dremel tool. TechDiamondTools.com sells a variety of diamond sprays, pastes, and dry powders for high-level polishing of various materials. Diamond sprays are particularly useful for polishing plastics because they are finer than the red polishing compound that typically comes with Dremel tools, which is intended for use on metals.
To use a diamond spray for polishing plastics with a Dremel tool, follow these steps:
- Choose the right diamond spray for your application. For example, Aka-Spray Poly and Mono diamond sprays are suitable for water-sensitive materials, while QATM's QPREP diamond spray is suitable for commissioning new polishing cloths.
- Prepare the surface to be polished by ensuring it is clean and free of any dirt or debris.
- If using a new polishing cloth, prime it with the diamond spray before starting. Hold the spray can about 20-25 cm over the polishing cloth and spray for about 2 seconds while moving the can over the entire surface of the cloth.
- Start polishing the plastic surface with your Dremel tool at a soft polish setting of 5,000 RPM. You can slowly turn up the speed if needed, but for best results, stay below 15,000 RPM.
- During preparation, apply the diamond spray to the polishing cloth to maintain the necessary level of diamonds for continuous high removal. Remember to use a suitable lubricant that suits the material you are polishing.
- Finish by buffing the plastic surface with a clean polishing cloth to remove any excess compound and achieve a smooth, polished finish.
Remember to always work in a well-ventilated area and wear appropriate safety gear, such as safety glasses and gloves, when using power tools and chemical compounds.

Finish by buffing with a polishing cloth
Once you're happy with the look of your plastic item, it's time to finish the job with a buff using a polishing cloth. Dremel's polishing cloth is soft and flexible, making it ideal for applying to contoured edges and curves. The cloth generates less heat during use, which is important as plastics are intolerant of heat buildup, which can cause optical distortion.
Before buffing, ensure that the plastic surface is smooth and clean. You can use a polishing compound to remove any remaining small imperfections. This solid paste can be used in combination with the cloth—simply hold the cloth in the compound while rotating, or rotate it by hand. Remember to use the compound sparingly, as a little goes a long way.
If you're using the red polishing compound that came with your tool, be aware that it's intended for use on metals, not plastics. For plastics, a diamond spray, paste, or dry powder will give you cleaner results. You can also use a cotton pad with a red polishing paste to smooth out deep scratches.
Now, you're ready to buff your plastic item with the polishing cloth. Start at 5,000 RPM for a soft polish, and slowly increase the speed if you wish, but for the best results, stay below 15,000 RPM. Finish up by gently buffing the plastic with the cloth, taking care not to press down too hard on the surface.
