There are a lot of ways to get Posca paint off fabrics or even erase Posca markers from different surfaces. We will discuss these tips below. But before that, let us go over the things you need to prepare first.

What to Prepare


Gather a soft cloth, some cotton balls, or a sponge, then prepare one of the following:

  • Rubbing alcohol
  • Acetone (nail polish remover)
  • Magic eraser
  • Fine-grit sandpaper
  • White vinegar and baking soda
  • Stain remover and laundry detergent
  • Soap and water

Posca pens are known for their water-based, opaque paint that adheres well to a variety of surfaces. But if you need to remove Posca pen markings, you can try following the procedures:

Method 1. Using Rubbing Alcohol


Surfaces: Any surface type except wool or silk

  1. Work in a well-ventilated space. Place a cloth under the stained area to catch any drips.
  2. Dip a cotton ball or cloth in rubbing alcohol. Test on a hidden area to make sure it won’t damage the surface.
  3. If safe, apply rubbing alcohol to the stained area using the cotton ball or cloth.
  4. Gently rub the stained area in a circular motion and gradually increase pressure.
  5. As the ink loosens, it may transfer onto the cloth. Replace the cloth or cotton ball as needed.
  6. Once the stain is gone, thoroughly rinse the area with water and pat dry.

Method 2. Using Vinegar and Baking Soda


Surfaces: Any fabric or surface type

  1. Mix equal parts white vinegar and baking soda to form a paste.
  2. Gently blot the stained fabric with the paste using a cloth.
  3. Leave the paste on the stain for about 15 minutes.
  4. Blot the stained area with a damp cloth to lift the paste.
  5. Wash the fabric as usual in cold water.
  6. If the stain remains, repeat the paste application and washing process.

Method 3. Using Acetone


Surfaces: Any surface type

  1. Test acetone on an inconspicuous spot to ensure surface compatibility.
  2. Dab a cotton ball or cloth with a small amount of acetone.
  3. Gently rub the ink stain with the acetone-soaked material.
  4. Gradually increase pressure while rubbing to loosen the paint.
  5. As the stain transfers, use clean sections of the cloth or cotton ball.
  6. Observe the stain and continue rubbing until it’s removed.
  7. After successful removal, rinse the spot with water and pat dry.

Method 4. Using Sandpaper


Surfaces: Hard surfaces such as plastic, metal, or wood

  1. Ensure the surface is clean and dry before beginning.
  2. Choose fine-grit sandpaper appropriate for the surface.
  3. Gently sand the stained area in a circular or back-and-forth motion.
  4. Frequently check to see if the Posca paint is being removed.
  5. If the paint persists, apply slightly more pressure.
  6. Once the stain is gone, lightly sand the area to smoothen any roughness.
  7. Wipe away any sanding residue and clean the surface.

Method 5. Using Magic Eraser


Surfaces: Walls or tiles

  1. Moisten the magic eraser with water until it’s damp.
  2. Gently rub the stained area using the damp magic eraser.
  3. Monitor the stain’s removal and adjust pressure as needed.
  4. As the stain lifts, wipe away the residue with a clean, damp cloth.
  5. If the stain remains, repeat the process until it disappears.

Method 6. Using a Stain Remover and Laundry Detergent


Surfaces: Any type of fabric

  1. Rub the stain using a brush. Ensure the brush has been immersed in the stain remover before you wash off denim or any other fabric stains.
  2. Double-check if the Posca paint is completely gone before manual- or machine-washing it. All fabrics are washable, so doing this should be fine.
  3. Wash the fabric in cold water to prevent setting any remaining stains.
  4. Add laundry detergent as usual to the washing machine.
  5. Avoid using hot water or a dryer, as heat can set stains.
  6. Hang the fabric to air dry or follow fabric care instructions.
  7. All the stains should wash out of fabric. But if there are any stains left, repeat the entire process.

Method 7. Using Soap and Water


Surfaces: Baby or adult skin; stains on glass

  1. Wet the affected skin area and apply soap to the marks.
  2. Gently rub the marks using your fingers, a soft cloth, or a sponge.
  3. Focus on creating a lather to help lift the paint.
  4. Rinse the spot with water to wash away the soap and loosened paint.
  5. Gently pat the skin dry using a clean, soft towel.
  6. Check if the Posca pen marks have been successfully removed.
  7. If any faint marks remain, you can repeat the washing process.

By meticulously following these comprehensive steps, you can effectively clean Posca pen marks from various surfaces and fabrics. Always prioritize caution and test on inconspicuous areas before full application.
