Painting plastic shutters can be a challenging task, especially if you want to avoid removing them from the house. While it is possible to paint over existing paint, you may encounter issues with peeling or poor adhesion. To get paint off plastic shutters, you can try using products like Goof Off, or even brake fluid, though the latter may not be worth the mess. Another option is to use a hand paint sprayer or a roller and brush for wider, flat surfaces. Before painting, it is crucial to clean the shutters and consider using a primer to ensure better adhesion and coverage.

What You'll Learn
Use rubbing alcohol and a cotton ball to test a small area first
If you're looking to remove paint from plastic shutters, one method is to use rubbing alcohol. This method is safe on plastics and can be used on acrylic paint. Begin by soaking a cotton ball in rubbing alcohol. It's important to test a small area first, so choose an inconspicuous spot on the shutter and rub the cotton ball over it to see how the shutter reacts. This is especially important if your shutters are black, as the alcohol may take some of the black colour off as well.
If the test is successful, continue by scrubbing the painted area with the alcohol-soaked cotton ball until the paint comes off. If you're dealing with a larger area, you may need to use a stiff-bristled brush instead. Keep applying the alcohol and scrubbing with new cotton balls until the paint is removed.
Once the paint is gone, wash the area with soap and water to ensure all the alcohol is gone, then dry it thoroughly. If there is still some residue, dip a cotton ball into the soap and water solution and rub at the area again.
As an alternative to cotton balls, you can also use a cloth soaked in denatured alcohol. Leave the cloth on the painted area until it dries, then repeat the process until the paint is gone.

Try a product like Goof Off or brake fluid
If you want to remove paint from plastic shutters, you can try a product like Goof Off or brake fluid. Goof Off is an aerosol remover that can be used on hard surfaces, including metal, glass, brick, and wood. It is a fast-acting adhesive remover that can be used to remove dried latex paint, adhesive, glue, asphalt, and tar. To use Goof Off, simply flip the straw down for a broad spray on larger areas or flip it down for a targeted application on smaller areas.
Before using any chemical product, it is important to take the necessary safety precautions. Always read and follow the label instructions carefully, and keep these types of products out of the reach of children. It is also recommended to work in a well-ventilated area and wear protective gear, such as rubber gloves and old clothes, to avoid splashing the product on your skin.
Brake fluid can also be used as an alternative to paint strippers for removing paint from small plastic objects. It works by loosening the paint and breaking down the adhesion between the paint and the surface. To use brake fluid for paint removal, start by washing the surface of the shutters with mild liquid soap and warm water to remove any dirt or debris. Rinse thoroughly and pat the surface dry with a paper towel.
Next, pour the brake fluid into a glass jar, ensuring that the fluid is suitable for use on plastic by testing it on a small section first. Submerge the shutters in the brake fluid and leave them for an extended period. If paint remains, submerge the shutters again for an additional 12 hours and then scrub the paint gently. Finally, rinse the shutters thoroughly and dispose of the brake fluid according to waste disposal regulations.
It is important to note that removing paint from shutters can be a big job, and it may be time-consuming and messy. Before attempting any paint removal method, consider whether it is necessary to remove the paint or if you can simply paint over it. If the paint is peeling or there are rough spots, you may want to consider sanding the shutters and then painting them. Additionally, if your shutters are faded, you can buy a good-quality spray-on car wax to make them look brand new again.

Clean with phosphate-based or solvent cleaners to remove mould-release agents
If you're looking to remove paint from plastic shutters without destroying them, there are a few methods you can try. One option is to use a phosphate-based or solvent cleaner to remove mould-release agents and any dirt or mildew from the plastic surface. This is an important step to ensure the new paint adheres properly and doesn't peel or crack.
Phosphate-based cleaners, such as Alconox® Powdered Precision Cleaner or Detonox® Ultimate Precision Cleaner, are effective in removing mould release agents from plastic surfaces. To use these products, you should immerse the shutters in a very hot solution (approximately 170ºF / 80ºC) of 2-3% phosphate-based cleaner, followed by a very hot rinse. This high temperature is crucial, as it helps to soften and emulsify the mould release agents, making them easier to remove. It is important to wear protective equipment when handling these chemicals.
Alternatively, you can opt for solvent cleaners, which are more effective than aqueous solutions due to their lower surface tension. Chlorinated solvents, in particular, can be useful for penetrating the porosity of the plastic surface. However, it is important to exercise caution when using these chemicals and consider outsourcing the cleaning to a professional company if the operation is large enough.
For a milder approach, you can try using rubbing alcohol on a small cotton ball, testing it on an inconspicuous spot first. This method may not be as effective for thick layers of paint, but it can help remove small spatters or mistakes. Additionally, warm soapy water can be adequate for removing mould release agents, especially if the contamination is not too heavy. Simple Green, Wite Tire Cleaner, and Purple Power are commercially available options with Butoxyethanol as the active ingredient.

Use a paint scraper to remove loose paint
If you are looking to remove paint from plastic shutters, one of the methods you can use is a paint scraper. This is a good option if you have many layers of paint that need removing. Before you start, remove any latches, brackets, or hinges from the shutters. Then, take a paint scraper and use it to gently eliminate loose paint or chips from the flat surfaces. Be careful not to press too hard, as this may scratch or indent the surface of the shutters.
A paint scraper is a good tool to have around, as it can be used for a multitude of tasks, such as pulling nails, cleaning rollers, opening cans, gouging, and more. They are also much more effective at removing loose paint than a putty knife. Once you have removed the majority of the loose paint with the scraper, you can use a sander and sandpaper to smooth out the remaining paint finish.
If you are unsure about using a paint scraper, you can test out other methods, such as using rubbing alcohol on a small cotton ball, or a product called Goof Off, which is designed to remove paint. You could also try brake fluid, but this may be messy.

Apply a plastic-safe household cleaner, then a primer
If you are looking to remove paint from plastic shutters, you can try a few different methods. It is important to note that some of these methods may be time-consuming or messy, and some chemicals can be toxic or damaging to the plastic. It is always good to test any product or solution in a small, inconspicuous area first.
Now, if you are looking to paint over existing paint, you can simply apply a plastic-safe household cleaner, then a primer, and finally, your chosen paint colour.
Firstly, you will want to clean the shutters. Use a plastic-safe household cleaner to wipe down the shutters, removing any dirt or debris. You can use a non-abrasive, all-purpose cleaner, or a gentle, natural cleanser like Tri-Sodium Phosphate. A simple paste of baking soda and water can also be effective. Gently rub the paste onto the shutters with a damp sponge, then wipe clean with a damp cloth.
Next, you will want to apply a primer. A primer will help to create an even finish and a deeper colour for your paint. You can buy a spray paint that includes a primer, like Krylon Fusion, or you can apply a separate coat of primer. If you are using a separate primer, allow it to dry before applying your paint.
After the primer has dried, you can begin painting. You can use a brush or spray paint, but spray paint is easier for quickly covering the nooks and crannies of the shutters. You may need to apply a second coat of paint for a deeper colour. Allow the paint to dry completely before deciding if a second coat is necessary.
And there you have it! A simple way to refresh the look of your plastic shutters.

If your shutters are new, check with the manufacturer to see if they need any special cleaning and follow their painting instructions. If they are old, clean them with a plastic-safe household cleaner to scrub any dirt or mildew from the plastic. If mildew or mould is present, kill it using a mixture of one part bleach to four parts water, then rinse with a hose and scrub the shutters with detergent and water.
You can use any quality 100% acrylic latex paint as a topcoat, but you must use a primer first. Krylon and Rustoleum both make paints and primers that bond well to vinyl and other plastics.
It is recommended to remove the shutters before painting, as it will be less stressful and take less work than trying to work around the shutter in place. However, if you want to paint them without removing them, carefully tape around the shutter with wide blue painter's tape and be careful when painting the edges that sit against the siding.
If the paint on your shutters is peeling, you can try to remove the old paint by hand or with a scraper. You can also try using a product like 3M Scuff It and a grey Scotch-Brite pad to clean and lightly scuff the shutters.
