An accidental ballpoint ink pen swipe can result in stains on rubber surfaces. Ingredients in the pigment cause it to adhere to surfaces, leading to a stain on your rubber item. Quick action to remove the ink stain helps remove it more easily and prevents it from spreading or transferring to nearby surfaces. Supplies in the home make effective remedies for removing the ballpoint ink stain from the rubber surface.
Rub the ballpoint ink stain on the rubber with butter. Smooth butter over the ink then place the rubber object outside in the sun or in a sunny indoor location. Allow the item to sit in the sun for one to three days so the butter and heat can soften the ink mark.
Dampen a clean cloth and wipe off the surface to remove the butter and as much ink stain as possible. Dry the rubber with another cloth.
Combine 1 tbsp. each ammonia and hydrogen peroxide in a bowl. Dampen a cloth with the ammonia solution and scrub the rubber to remove remaining ink. As the ink stain lifts, move to a clean portion of the cloth and continue to scrub until the stain is gone.
Wash the rubber surface with a damp cloth and one drop dish washing detergent. Remove the ammonia solution and any oil residue from the butter. Dry the rubber with a cloth, then allow to air-dry the rest of the way.
