Removing old paint from a plastic hobby horse can be a fun DIY project, but it requires careful preparation. Before starting, it is important to gather the necessary tools and select a suitable workspace. The first step is to clean the toy thoroughly with soapy water or a degreaser and let it dry completely. If the toy has moving parts, they should be carefully disassembled to avoid sealing the joints during the painting process. Once the horse is clean and dry, the original paint can be removed using a solvent, brake fluid, or by sanding it off. However, one should be cautious when using a solvent as it may damage the plastic components. After removing the old paint, the surface of the plastic horse can be prepared for a new coat of paint by scuffing it with fine steel wool or sanding it with fine sandpaper to create a rough surface for the paint to adhere to.

What You'll Learn
Use brake fluid to remove paint
When removing old paint from a plastic hobby horse, it is important to be cautious as some solvents can damage the plastic components. While brake fluid can be used to strip paint, it is a toxic substance that requires careful handling and may not be suitable for use on plastic. If you decide to use brake fluid, follow these steps:
First, ensure you are working in a well-ventilated area and wear protective gear, including thick gloves and a mask. Brake fluid is toxic, so take the necessary precautions to avoid inhalation or direct skin contact.
Next, clean the hobby horse thoroughly with soapy water and allow it to dry completely. This step is crucial as any remaining dirt or grease can affect the paint removal process.
Before applying the brake fluid, test it on a small, inconspicuous area of the plastic to ensure it does not cause damage or discolouration. Apply a small amount of brake fluid to a cotton ball or soft cloth and rub it gently onto the test area. Wait for at least 8-12 hours and then inspect the spot for any signs of melting or blurriness. If the plastic remains intact, you can proceed with the next steps.
Now, apply the brake fluid generously to the painted areas of the hobby horse. You may use a brush or a cloth to do this, ensuring that the fluid covers the paint evenly. Allow the brake fluid to sit for a few hours—the exact time will depend on the thickness of the paint, but generally, 8-12 hours should be sufficient.
After the waiting period, use a scraper or a damp cloth to remove the softened paint. It should come off easily, but be careful not to apply too much force as you don't want to scratch the plastic. Once the majority of the paint has been removed, you can use a soft-bristled brush to gently scrub away any remaining residue.
Finally, clean the hobby horse again with soapy water to remove any traces of brake fluid and allow it to dry. You may then choose to apply a plastic-friendly primer and paint to give your hobby horse a fresh new look!

Clean the toy with soapy water
Before you start the paint job, it's important to clean the hobby horse thoroughly. This will ensure that the new paint adheres well to the surface and that any dirt or grime is removed. Here's a step-by-step guide to cleaning your plastic hobby horse with soapy water:
Step 1: Gather Your Materials
You'll need a bucket or sink, warm water, and a mild dish soap or detergent. You may also want to use a soft sponge or scrubber to gently clean the horse without scratching the surface.
Step 2: Disassemble if Necessary
If your hobby horse has any moving parts, carefully disassemble them before cleaning. This will help you reach all the nooks and crannies and prevent sealing the joints when you paint the toy. Make sure to pay attention to any instructions or manuals that came with the hobby horse for specific disassembly instructions.
Step 3: Soak or Immerse the Toy
Fill your bucket or sink with warm water and add a generous amount of mild dish soap or detergent. You can also use a child-safe disinfectant if you prefer. If your hobby horse is small enough, you can fully immerse it in the soapy water. Let it soak for several minutes to loosen any dirt or grime. If it's too large to immerse, use a sponge or scrubber dipped in the soapy water to wipe down the horse.
Step 4: Gently Scrub the Toy
Use your soft sponge or scrubber to gently scrub the surface of the hobby horse. Pay extra attention to any areas with ground-in dirt or tough stains. You can also use a stiff-bristled brush for tougher stains, but be careful not to scratch the plastic surface. For intricate details or hard-to-reach areas, you can use a soft-bristled toothbrush.
Step 5: Rinse and Dry
After scrubbing, thoroughly rinse the hobby horse with clean water to remove any soap residue. Ensure that you rinse all surfaces, as soap residue can attract dirt and dust. Once rinsed, dry the hobby horse completely before proceeding to the next step of your project. You can air-dry it or use a soft cloth to gently wipe away excess water.
Additional Tips:
- If your hobby horse has stickers or decals, be cautious when cleaning with soapy water, as the water and dish soap can affect the adhesive and cause the stickers to come off.
- For a more natural cleaning approach, you can use a vinegar and water solution (one part vinegar to ten parts water) to clean and disinfect the hobby horse. Rinse and dry thoroughly after using this solution.

Sand the plastic surface
Sanding is an essential step when preparing plastic for painting. It is important to thoroughly sand the plastic to a matte finish, as paint adheres far better to rougher, matte surfaces than to glossy plastics. If the paint isn't sticking to the plastic, it is usually because the surface is too glossy.
Before sanding, ensure that the plastic is clean and dry. You can use a bucket with warm water and a little dish soap to scrub the plastic with a rag or sponge. Rinse the plastic with cool, clean water to ensure no suds remain.
When sanding, use fine-grit sandpaper, such as 180- to 220-grit sandpaper, to prevent marring the surface. Do not vigorously sand the plastic, as this may create enough friction to melt the plastic. Lightly sand all surfaces by hand, or use a random orbital sander for larger areas. If the plastic has curved surfaces or small crevices, it may be easier to use sandpaper instead of a sanding block.
After sanding, wipe the plastic with a clean rag and mineral spirits or isopropyl alcohol to remove any fine plastic dust produced by the sanding process. This step is crucial, as it will ensure a smooth finish when painting. Take the plastic to a well-ventilated area, such as outdoors on a dry day, to ensure proper ventilation during the sanding and painting process.
Once the plastic is clean, dry, and sanded, you can begin the priming and painting process. It is recommended to use a primer and paint specifically designed for plastic to ensure the best adhesion and finish. Spray a thin, even layer of primer, working in sections from left to right, and allow it to dry completely before applying the paint.
If you encounter any dried-on drips or drops after painting, you can sand them down flat once the paint is 100% dry and hard. This step will ensure a smooth finish. After sanding, apply a second coat of paint, lightly misting the surface from a distance of about 12 inches.

Use a paint stripper or oven cleaner
If you want to remove old paint from a plastic hobby horse, one option is to use a paint stripper or oven cleaner. This method can be effective, but it's important to choose a product that is safe for use on plastic and to follow the necessary precautions.
Before using any paint stripper or oven cleaner, be sure to read the labels carefully and choose a product that is suitable for plastic. Some paint strippers and oven cleaners may contain harsh chemicals that can damage plastic, so it's important to select a product that is specifically designed for use on this material. Check for any safety warnings and make sure the product is non-toxic and environmentally friendly.
Once you have chosen a suitable paint stripper or oven cleaner, prepare the work area by putting on protective gear, such as gloves and eye protection. Work in a well-ventilated area or outdoors to avoid inhaling fumes. If working indoors, open windows and doors to ensure adequate ventilation.

Some products may require dilution or specific application methods, so be sure to read and follow the directions carefully. Allow the product to work on the paint for the recommended amount of time, which may vary depending on the type of paint and thickness of the coating.
After the paint stripper or oven cleaner has had sufficient time to work, use a scraper or old toothbrush to gently remove the softened paint. Be careful not to scratch or damage the plastic surface underneath. Rinse the hobby horse with clean water and dry it thoroughly before proceeding with any further steps, such as repainting or refinishing.
It is important to note that using a paint stripper or oven cleaner may not always be the best option for removing paint from plastic, as some sources suggest that it may not be effective or may damage the plastic. Therefore, it is crucial to test the product on a small, inconspicuous area first to ensure that it does not harm the plastic surface. Additionally, always prioritize your safety by working in a well-ventilated area and following the instructions on the product label.

Prime and paint
Before you begin painting, it is important to prep the hobby horse. Start by cleaning the toy thoroughly with soapy water or a degreaser like Blue Dawn, and then let it dry completely. If there are any old decals, gently scrub or scrape them off and replace them with new ones if desired. If your hobby horse has moving parts, carefully disassemble them to prevent sealing the joints when you paint. Once the surface is clean and dry, scuff it with fine steel wool. Then, clean the hobby horse again with denatured alcohol.
Now, you are ready to prime the hobby horse. It is recommended to use a spray primer designed for plastic, such as Krylon or Rustoleum Universal spray paint. You can find these primers at most hardware stores. Before priming, make sure to work in a well-ventilated area and read the safety instructions on the product. Apply light layers of primer to avoid drips and runs, and allow each layer to dry completely before applying the next.
After priming, you can start painting your hobby horse. Choose a paint that is specifically designed for use on plastic to ensure better adhesion and durability. You can use spray paint or regular paint, depending on your preference. If using spray paint, follow the same instructions as the primer, applying light layers and allowing each layer to dry before applying the next. If using regular paint, you may need to thin it with a suitable solvent before application.
When painting, you can get creative with the colours and design. Consider using colours typically found on carousel horses, such as black, white, purple, and gold. You can tape off certain areas of the hobby horse to create different colours and designs. For example, you can tape off the saddle and face to apply a different colour. Feel free to add details such as pink in the mouth, nose, and ears for added realism. You can also hand-paint the eyes and other small details to give your hobby horse a unique expression.
