Your ink eraser may not be working for a few reasons. It could be that the eraser is old and has dried out, or it may have been exposed to extreme temperatures which can affect its performance. Additionally, the type of ink you are trying to erase may not be compatible with the eraser. It's also possible that the paper you are trying to erase on is not suitable for the eraser to work effectively. Consider trying a different eraser or testing it on a different type of paper to see if that improves its performance. **

An ink eraser works by using a combination of abrasion and chemical solvents to remove ink from paper. The abrasive material on the eraser rubs against the paper, breaking down the ink particles and lifting them off the surface. At the same time, the chemical solvents in the eraser help to dissolve and lift the ink, making it easier to remove. This combination of abrasion and solvent action allows the ink eraser to effectively "erase" ink from the paper. **

Red ink, specifically Eosin, cannot be erased with an ink eraser because it is a dye-based ink. Dye-based inks are absorbed into the paper fibers, making it difficult to remove them completely. Ink erasers work by lifting the pigment of the ink off the paper, but they are not effective on dye-based inks like Eosin. As a result, attempting to erase red ink with an ink eraser will likely result in smudging and spreading the ink, rather than completely removing it. **

To remove an ink stain with an ink eraser, start by gently rubbing the eraser over the stained area in a circular motion. Be careful not to rub too hard, as this could damage the fabric. Continue to rub the eraser over the stain until it begins to fade. Once the stain has lightened, wash the fabric as usual to remove any remaining ink and eraser residue. If the stain persists, you may need to repeat the process or try using a different stain removal method. **

To remove ink eraser stains from the floor, you can start by gently scraping off as much of the eraser residue as possible using a plastic scraper or a credit card. Then, dampen a clean cloth with warm water and a mild detergent, such as dish soap, and gently scrub the stained area. If the stain persists, you can try using a mixture of equal parts water and white vinegar or rubbing alcohol to spot treat the area. Remember to test any cleaning solution on a small, inconspicuous area of the floor first to ensure it does not cause any damage. **

To remove ink from an ink eraser on the ceiling, you can start by gently scraping off as much of the ink as possible using a plastic scraper or a credit card. Then, mix a small amount of dish soap with warm water and use a clean cloth to gently dab at the remaining ink stain. If the stain persists, you can try using a small amount of rubbing alcohol on a cotton ball to carefully dab at the ink until it lifts off. Be sure to test any cleaning solution on a small, inconspicuous area first to ensure it doesn't damage the ceiling surface. **

To remove an ink eraser stain from fabric, start by gently scraping off any excess eraser residue with a dull knife or spoon. Then, blot the stained area with a clean cloth dampened with rubbing alcohol, working from the outside of the stain towards the center to prevent spreading. Continue blotting with a clean cloth until the stain is lifted. Finally, launder the fabric as usual. If the stain persists, consider using a stain remover or seeking professional help. **
