Use nail polish remover with acetone
To dissolve ink but not the plastic underneath, you can use nail polish remover with acetone. Nail polish remover comes in two forms: with acetone and without. The acetone-based version is the most well-known type and has a strong, distinctive smell. It is a powerful solvent found in other household and industrial products like paint remover, cleaners, and rubber cement.
Nail polish remover with acetone can be used to dissolve ink stains on plastic. To do this, soak a lint-free cloth in the remover and wrap it around the stained area. Leave it for a few minutes, and the ink will start to come off. You can also use a cotton ball soaked in nail polish remover, followed by warm soapy water, and then wipe the area clean.
Acetone is also effective at removing ink stains from glass lab equipment, as well as grease and other residues, including soap. It can also be used to clean china cups and plates.
It is important to note that while acetone is generally safe for use on plastic, it is always recommended to wear gloves and a mask when working with any chemicals or cleaning agents. Additionally, acetone should not be used on certain types of plastic, such as polycarbonate, acetate, or vinyl, as it may cause cracking or discolouration. Always spot-test on an inconspicuous area first.

Try baking soda
Baking soda, also known as sodium bicarbonate, is a mildly abrasive salt that causes organic compounds to dissolve in water. Its abrasive properties help break down ink, while its mild nature ensures that plastic remains unharmed.
To use baking soda to dissolve ink, but not plastic, you can try the following methods:
Baking Soda and Water
Mix a small amount of baking soda with water to make a paste. Apply the paste to the ink stain on the plastic surface using your fingers or a soft cloth. Gently rub the paste into the stain in a circular motion. Allow the paste to sit for a few minutes, then wipe it away with a damp cloth. Finally, rinse the area with clean water and dry it thoroughly.
Baking Soda, Toothpaste, and Water
Mix one tablespoon of baking soda with white, non-gel toothpaste in a small container until they form a thick paste. Apply the paste to the ink stain and let it sit for five to ten minutes. Dip a dish sponge or cloth in water and gently scrub the paste off the affected area. Rinse the item with clean water to ensure the stain is completely removed.
Baking Soda, Hydrogen Peroxide, and Paper Towel
Sprinkle baking soda on the ink stain, then cover it with a white paper towel. Pour a small amount of hydrogen peroxide onto the paper towel and let the solution sit overnight. This method is suggested for removing plastic bag ink stains.
Baking Soda and Olive Oil
Mix baking soda and olive oil together to make a thick paste. Apply the paste to the ink stain and let it sit. This method is also suggested for removing plastic bag ink stains.
It is important to note that while baking soda is generally safe for most plastics, it is always a good idea to test your chosen cleaning method on a small, inconspicuous area first to ensure it does not damage or discolour the surface. Additionally, wearing gloves and a mask during the cleaning process is recommended to ensure your safety.

Use diluted bleach
When it comes to removing ink from plastic surfaces, diluted bleach can be an effective solution. Here's a step-by-step guide on how to use diluted bleach to dissolve ink without damaging the plastic:
Firstly, gather the necessary materials: gloves, eye protection, a well-ventilated work area, and a diluted bleach solution. For the bleach solution, mix one part bleach to nine parts water. This dilution is important to ensure that the bleach is effective in removing the ink but not too strong that it damages the plastic. Always wear protective gear when handling bleach to avoid skin and eye irritation.
Begin by testing the solution on a small, inconspicuous area of the plastic surface. This is crucial to ensure that the bleach solution does not adversely affect the plastic. Apply a small amount of the diluted bleach to a cotton ball or soft cloth, and gently rub it onto the test area. Wait a few minutes to ensure that the plastic is not reacting negatively to the bleach.
If the test area shows no signs of damage, proceed with the ink removal process. Soak a clean cloth or sponge in the diluted bleach solution, making sure it is thoroughly wet. Gently blot the ink stain with the cloth, working from the outside edges of the stain toward the center to avoid spreading the ink further. You may need to apply gentle pressure and repeat the blotting process several times to fully lift the ink.
After removing the majority of the ink, rinse the area with clean water to remove any residual bleach. This step is important to neutralize the bleach and ensure it doesn't continue to react with the plastic. Finally, dry the plastic surface with a soft, clean cloth. If any ink remains, repeat the process, but be cautious not to over-saturate the plastic with bleach, as prolonged exposure may eventually cause damage.
Using diluted bleach is a safe and effective way to dissolve ink on plastic surfaces. Remember always to work in a well-ventilated area and wear protective gear. With careful application and testing, you can successfully remove ink stains without damaging the plastic. This method is particularly useful for removing ink from plastic items like pens, containers, or toys.

Try ethyl acetate
If you're looking to dissolve ink but not the plastic it has stained, you might want to consider using ethyl acetate. It is a solvent that can be used to dissolve a variety of substances, including some inks. Ethyl acetate has a strong solubility and is often used to dissolve materials such as vegetable oil, rosin, natural resins, and rubber.
To use ethyl acetate to dissolve ink, you should first set up your workspace in a well-ventilated area or outdoors to avoid inhaling the fumes. Wear gloves and a mask to protect yourself from the chemicals. Then, follow these steps:
- Locate the ink stain on the plastic surface and assess its size and severity.
- Apply a small amount of ethyl acetate to a clean cloth.
- Rub the cloth over the stained area using circular motions until the ink starts to fade and eventually disappears completely.
- Wipe the area with a damp cloth and let it dry.
It is important to note that, while ethyl acetate is a powerful solvent, it may not work on all types of ink. Some inks, such as printer or pen ink, are highly concentrated and may require multiple applications or a different solvent altogether. Additionally, always spot-test the ethyl acetate on an inconspicuous part of the plastic item first to ensure it does not cause any discolouration or damage.

Use pure ethanol
Pure ethanol is one of the many solvents that can be used to dissolve ink from plastic. Other solvents that can be used include acetone, hydrogen peroxide, chlorine bleach, denatured alcohol, and ordinary rubbing alcohol.
When using pure ethanol to dissolve ink, it is important to follow certain steps to ensure the process is safe and effective. Firstly, it is recommended to spot-test the ethanol on an inconspicuous part of the plastic item to ensure that it does not cause any undesired side effects, such as discolouration or deterioration. This is especially important when dealing with sensitive plastics such as polycarbonate, acetate, or vinyl, which can be easily damaged by certain solvents.
Once it has been established that ethanol is safe to use on the plastic surface, the affected area can be wiped repeatedly with a cloth soaked in ethanol. It is important to work the solvent into the stain using smooth, circular motions until the ink disappears completely. If the ink is particularly stubborn, it may be necessary to re-wet the cloth and repeat the process.
In some cases, pure ethanol may not be strong enough to completely dissolve the ink. In such cases, it may be necessary to resort to a harsher solvent or a different method. For example, one source suggests using a combination of acetone and ethanol, or a product called "Goo Gone", to remove permanent marker from plastic. Another source recommends sanding and polishing with automotive resin polish to remove ink printing from plastic.
It is worth noting that while ethanol and other solvents can be effective in removing ink from plastic, they may not always work 100%. Additionally, some inks may be more difficult to remove than others, such as printer or pen ink, which are highly concentrated and hard to dissolve. Therefore, it may require some experimentation to find the most effective method for removing ink from plastic without causing any damage to the surface.
