What You'll Learn

Using toothpaste
Toothpaste is a mild abrasive that can be used to clean stains from plastic paint palettes. It is important to note that only whitening toothpaste should be used for this purpose, as gel-based toothpaste will not have the same effect.
To start, ensure that your plastic paint palette is clean and dry. Combine equal parts of toothpaste and baking soda on the palette to form a paste. Next, use a toothbrush or a piece of kitchen paper to gently scrub the mixture in circular motions over the stained area. The colour should lift immediately. If not, you may need to soak the palette in warm water.
Once you have removed the stain, thoroughly clean the palette with warm water and dry it with a cloth or paper towel. It is important to ensure that the palette is completely dry before using it again, as using a damp palette can cause paint to run and create a mess.
Toothpaste is an effective and affordable way to remove stains from plastic paint palettes, helping to restore them to their original white and shiny condition.

Soaking in soap and hot water
First, fill a basin or sink with hot water. The water temperature should be as hot as you can comfortably manage without scalding yourself. Add a generous amount of soap to the water. You can use a mild dishwashing liquid or a specific brush cleaner soap, such as Master's Brush Cleaner. Swirl the water gently to create a soapy solution.
Next, place your stained plastic paint palette into the basin or sink, ensuring it is fully submerged in the soapy water. If your palette has wells or compartments, make sure they are filled with the soapy water too. Allow the palette to soak for a while, giving the soap time to work on breaking down the stains. The duration of the soak will depend on the severity of the stains. For light stains, a quick soak may be sufficient, while deeper stains may require a longer soaking time.
During the soaking process, you can use a soft cloth or sponge to gently rub the stained areas of the palette. This can help speed up the stain removal process. Be careful not to use anything abrasive, as this may damage the surface of your palette. If the stains are particularly stubborn, you can use a brush to gently scrub the affected areas. Ensure you only use soft-bristled brushes to avoid scratching the plastic.
After soaking and gently rubbing the stains, thoroughly rinse the palette with clean water. Inspect the palette to see if any stains remain. If some stains persist, repeat the soaking, gentle rubbing, and rinsing process until they are removed.
Finally, dry your palette thoroughly before using it again. You can use a soft cloth or simply let it air dry.
By following these steps, you can effectively remove stains from your plastic paint palette using soap and hot water. This method is a gentle and affordable way to keep your art equipment clean and well-maintained.

Using a melamine foam sponge
A melamine foam sponge is an effective way to remove stains from a plastic paint palette. This method is also known as a "magic eraser". The melamine foam is an abrasive surface, so it will dull the finish of your palette. If this is not desirable, you may want to try a different method.
To use a melamine foam sponge, first soak the sponge in water and squeeze out any excess. Then, gently wipe the palette with the sponge until the stains are removed. You can also use a dry melamine foam sponge and simply wipe the palette with it, but this may be less effective for removing tough stains.
It is important to note that some people have reported allergic reactions to the ingredients in the sponge, so it is important to be cautious when using this method and to avoid getting the sponge on your skin. In addition, the sponge should only be used on the palette and not on the paper, as it can lift paint and damage the paper.
The Mr. Clean brand of melamine foam sponge is recommended by some artists, and it is suggested that you use the original version, as other versions may contain additional cleansers.

Applying baking soda
Baking soda is a versatile household staple that can be used for cleaning, stain removal, and even as a substitute for baking! When it comes to removing stains from plastic paint palettes, baking soda can be an effective solution. Here's how you can apply baking soda to get rid of those stubborn paint stains:
Step 1: Create a Baking Soda Paste
Mix equal parts baking soda and water to form a paste. The amount you need will depend on the size of your palette and the extent of the staining. For a small palette with light staining, a few tablespoons of each should be sufficient. You can adjust the quantities as needed.
Step 2: Apply the Paste
Using your fingers or a soft cloth, gently rub the baking soda paste onto the stained areas of your plastic paint palette. Make sure to cover all the stained portions evenly. If you have thick or stubborn stains, you can let the paste sit for a few minutes to allow it to penetrate the stain.
Step 3: Scrub Gently
Once the paste has been applied and has had a chance to work its magic, it's time to scrub. Use a damp cloth or sponge to gently scrub the stained areas in a circular motion. Be careful not to scrub too aggressively, especially if your palette has a delicate finish, as this may scratch the surface. If the stains are particularly stubborn, you can use an old toothbrush for more targeted scrubbing.
Step 4: Rinse and Dry
After scrubbing, rinse the palette thoroughly with clean water to remove any residue. Ensure that all traces of baking soda and paint stains are washed away. Finally, dry your palette with a soft cloth or let it air dry.
Additional Tips:
- For tougher stains, you can try using a slightly more abrasive tool, such as a melamine foam sponge, but be cautious as it can dull the glossy finish of your palette.
- If you want to avoid scratching your palette, opt for a gentle abrasive like toothpaste, especially the whitening kind, which can be rubbed onto the palette with a piece of kitchen paper.
- Baking soda can also be used to clean paint stains from metal hardware. Create a solution by bringing a pot of water to a low boil and adding baking soda without stirring. Soak the metal hardware in this solution to remove paint.

Using brush cleaner
Using a brush cleaner is an effective way to remove paint stains from a plastic paint palette. While some people opt for natural methods like olive oil, or simply washing the palette with water, a brush cleaner can be a quick and easy way to remove dried paint.
One such product is the Turner Colour Works Palette Cleaner, which comes in a 40ml jar. This product can be used to remove paint stains and paint residue from plastic palettes. To use it, simply dip a clean soft cloth into the cleaner and gently rub the palette clean. Do not dilute the product. One user review states that the product works well, but it did not work on their traditional acrylic paints.
Another option is to use a paintbrush cleaner, such as turpentine or another oil paint cleaner. Moisten a cloth with the cleaner and gently wipe the palette to dissolve the remaining paint. Be cautious when using highly flammable solvents, and always wear gloves for protection. Once the paint has been dissolved, rinse the palette with water and let it air dry completely before using it again.
If you are looking for a more natural method, you can try using vinegar. Soak the palette in vinegar for 24 hours, and then scrub the paint away.
