Removing paint from large outdoor plastic yard figures can be tricky, but it's not impossible. Before you begin, it's important to identify the type of plastic you're working with, as different plastics require different care. Some common household products that can be used to remove paint from plastic include rubbing alcohol, nail polish remover, and paint thinner. It's important to wear protective gear, such as gloves and a respirator mask, when working with harsh chemicals to avoid inhaling fumes or damaging your skin. Additionally, it's a good idea to test your chosen solvent on a small, inconspicuous area of the plastic first to ensure it won't cause any damage. Once you've chosen your solvent, simply apply it to the painted area and scrub firmly with a rag or brush until the paint comes off. With a bit of elbow grease, you can restore your large outdoor plastic yard figures to their former glory!

What You'll Learn
Identify the type of plastic
There are several methods you can use to identify the type of plastic your yard figure is made of. Firstly, look out for a resin identification code. Many plastic products have a number, the "resin identification code", surrounded by a chasing arrows symbol. This is often moulded, formed, or imprinted on the bottom of the product. These codes were developed by the plastics industry to facilitate recycling. However, they do not guarantee recyclability and do not indicate the safety of the plastic.
Another easy way to identify the type of plastic is by establishing whether it floats or sinks. While there are exceptions, polyolefins generally float in water, and the rest generally sink. Polyolefins include High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), and Polypropylene (PP). So, if a piece of plastic floats, it is likely one of these three types.
You can also identify plastics by their appearance and feel. For example, polyethylene has a smooth texture and is flexible but can leave marks. LDPE is thin and can crumble in your hands, and it also crackles. In contrast, HDPE is tougher to deform and usually has a translucent and milky white coating. Polypropylene is bendable but will not break easily.
A scratch test can also indicate the type of plastic. Use your fingernail or a knife to scratch the surface. If it leaves a mark easily, it is likely LDPE or PP. If it does not leave a mark, it is likely PET or HDPE.
Finally, you can try a burn test. However, this method is not recommended due to the harm it can cause to your health and the environment. It also may not work for all types of plastics. If you do attempt this test, always do so in a well-ventilated area and wear protective clothing. A blue flame with yellow tips indicates polyethylene, while yellow flames with green tips point to PVC plastic. If it burns with a yellow flame and smells like burning candles or wood, it is likely PS.

Use a plastic scraper or fingernail to scrape off the paint
If you're looking to remove paint from large outdoor plastic yard figures, one method is to use a plastic scraper or your fingernail to gently scrape off the paint. This approach is particularly useful for flat surfaces when using a plastic scraper, as the straight edge won't scratch the surface. For curved areas, like toys and models, your fingernail might be more effective. Hold the scraping tool at a slight angle and carefully push it under the paint.
Before you start scraping, you can make the process easier by applying certain substances to the painted area. One option is to soak the area in soapy water or vegetable oil, then try scraping again. For small plastic items, you can submerge them in a container of warm, soapy water for around 20 minutes. For larger surfaces, apply vegetable oil, cover with plastic wrap, and let it sit for about 10 minutes before scraping. Alternatively, you can try soaking the plastic in hot water with equal parts baking soda and vinegar.
If the paint is particularly stubborn, you might need to use a solvent in conjunction with a scraping tool. Be cautious, though, as some solvents can damage or melt certain types of plastic. Always test your chosen solvent on an inconspicuous area first. If the plastic changes colour or texture, or if it indents when you press your fingernail into it, opt for a different solvent. Remember to wear protective gear, including gloves and a respirator mask, when handling solvents.
Some common solvents used to remove paint from plastic include rubbing alcohol, nail polish remover (acetone), paint thinner, and lacquer thinner. While these can be effective, they may damage some plastics. For instance, acetone and lacquer thinner can dissolve or melt plastic. A safer option for larger, harder plastic surfaces is a professional paint remover designed for polycarbonate.

Soak in warm, soapy water
Soaking in warm, soapy water is an effective method for removing paint from plastic surfaces. This technique is particularly useful for large outdoor plastic yard figures, as it helps to loosen dried paint, making it easier to scrape or scrub away.
To start, fill a bucket or container with warm water and add a few pumps of dish soap or a squirt of liquid soap. Ensure the water is warm, as this will help to soften the paint. Completely submerge the item in the soapy water and let it soak for at least 20 minutes. If the paint is particularly stubborn, you may need to let it soak for longer. For small items, you can use your fingers to rub the paint gently while the item is submerged. For larger items, use a sponge to wipe down the surface, applying a little elbow grease to see if the paint comes off.
If the paint is still not coming off easily, you can try adding a paint-softening agent to the warm, soapy water. Vegetable oil, for instance, can be used to soften the paint. Soak a piece of cloth or a sponge in the warm, soapy water, squeeze out the excess, and then wipe down the painted area. You can also try adding vinegar to the warm, soapy water to help break down the paint. Soak the item in this solution for a while and then scrub with a non-abrasive sponge.
After soaking, you can try using a plastic scraper, putty knife, or a stiff-bristled toothbrush to gently scrape or scrub away the paint. Be careful not to apply too much pressure, especially if the plastic is thin or fragile, as this could damage the item. If there is still paint or residue remaining, repeat the soaking and scraping process until the paint is completely removed. Finally, rinse the item with fresh water to remove any leftover soap or paint residue and let it air-dry or dry it with a towel.

Use a non-abrasive cleaner
If you're looking to remove paint from large outdoor plastic yard figures, one option is to use a non-abrasive cleaner. This method is ideal if you want to avoid using harsh chemicals that could potentially damage the plastic. Before you begin, it's important to identify the type of plastic and paint you're dealing with, as different types of plastic require different care. For instance, thinner polyethylene, polypropylene, acrylic, and fiberglass may allow you to use stronger solvents. Water-based paints like latex or acrylic tend to have a duller sheen and fade over time, while oil-based paints are glossier and yellow as they age.
Once you've identified the plastic and paint type, you can choose an appropriate non-abrasive cleaner. One option is to use a simple application of rubbing alcohol, which can help loosen unwanted paint. Be sure to wear a face mask and gloves to protect yourself from the fumes and your skin from the alcohol. Follow the printed instructions for safe use, pour the alcohol over the paint, and scrub firmly with a rag. You may need to be persistent, but eventually, you'll be rewarded with a clean, paint-free surface.
Another non-abrasive cleaner you can use is distilled white vinegar, which is particularly effective for removing latex paint. Simply apply the vinegar to the paint and wipe it away with a damp cloth. If you're dealing with a large area covered in old paint, you may want to try a professional paint remover, such as Soy-Gel Professional Paint Remover, which can safely remove paint from harder plastics like polycarbonate. Just be sure to wear protective gear and work in a well-ventilated space when using these products.
If you're looking for a more natural solution, you can create a paste made of baking soda and water. Apply this paste to the painted area and gently rub it with a damp sponge. For tougher stains, let the paste sit until it dries before wiping it off. This method is gentle yet effective and is a great option for those who want to avoid using harsh chemicals. Always remember to test any cleaning solution on a small, inconspicuous area first to ensure it won't damage the plastic.
No matter which non-abrasive cleaner you choose, always make sure to rinse the item with water to remove any soap or cleaner residue. For larger items, you can use a bucket of water or a hose to rinse them off. Then, let the item air dry or dry it with a towel. By following these steps and choosing the right non-abrasive cleaner for your specific plastic and paint type, you can effectively and safely remove paint from large outdoor plastic yard figures.

Rinse and dry
Once you have applied the chosen method to remove the paint from your plastic yard figures, you will need to rinse and dry them. Rinsing is an important step to ensure that all the paint and residue from your chosen solvent are removed. For larger items, such as your yard figures, rinsing with a hose is a convenient option. Alternatively, you can pour a bucket of water over them.
After rinsing, you can either let the item air-dry or use a towel to dry it. If your plastic yard figures are electronic, it is important to wait until they are completely dry before re-inserting the batteries or plugging them back in.
To ensure a truly smudge-free finish, you may want to consider using a non-abrasive all-purpose cleaner. Spray the cleaner onto the surface and gently wipe it clean with a damp sponge or a soft cloth. You can also create a paste with three parts baking soda to one part water. Apply this paste to the plastic and gently rub it with a damp sponge. For more stubborn stains, allow the baking soda mixture to dry before wiping it off.
It is worth noting that some solvents may need hours before they have an adverse effect on your item. Therefore, even after rinsing and drying, it is important to keep an eye on your yard figures and be vigilant for any changes in colour, texture, or indentation. If you notice any of these changes, it is recommended to use a different solvent.
