By twiddling these three components, the manufacturers can make an ink that disappears when enough heat is applied and reappears when sufficiently cold. When you erase with the rubber, the friction creates heat which changes the acidity of the ink and makes it invisible. When it is cooled down, the acidity changes back and the ink becomes visible again. Sign up to join this community. The best answers are voted up and rise to the top.

Use brake fluid to remove pen ink from the sheet of paper easily. Use acetone to erase ink. Most nail polish remover is made of acetone, and this can be used to remove ink from paper.
Apply a small amount of acetone to a cotton swab, and rub into the ink you're trying to erase. Blue ink is more easily erased than black ink. Try rubbing alcohol to erase ink. You can apply isopropyl rubbing alcohol to any paper you're trying to erase the ink from. If you only have a small amount of ink to erase, use a cotton swab. If you want to erase most of the ink from a page, soak the paper in a small washing tray for 5 minutes. Avoid any rubbing alcohol that contains scents or dyes.
Make sure you cover any area of the paper you don't want to erase. Apply lemon juice to your ink stain. Pour a small amount of lemon juice into an 8-oz jar. Dip a cotton swab into the lemon juice. Then, wipe the wet cotton gently across the inked paper you're trying to erase. Be gentle, especially when erasing ink from fine paper. Heavy-weight paper will stand up to pen erasure more readily than light-weight paper.
Mix baking soda and water to a thin paste. Mix it up in a small glass bowl for best results. Use a clean, white cotton cloth to dab your baking soda paste onto the inked paper. Gently rub the paste into the ink you'd like to erase. This works best if your toothbrush bristles are still relatively intact, not too frayed.
Allow the paper to dry well. There's no need to rinse the baking soda off. The water will evaporate, and the baking soda will simply fall off the page. Method 2. Use a simple blade to erase ink. This method works best for printed ink and use only when you need to remove only a few letters.
Hold the blade vertical to the paper and rub gently. Do not press the blade very hard on paper or you get off layers of paper.
Use a special ink eraser. If you are using erasable ink, you can easily erase it with an ink eraser. Erasable ink is typically blue, not black, and will be identified as 'erasable' in its packaging.
It's also often found like a pencil, with ink on one end and an eraser on the other. It's possible to erase ink using a vinyl eraser, but be careful. This eraser is very rough and can easily rub away the paper itself along with the ink you're erasing. Sand ink off using sandpaper. Use a triple-ought sandpaper and a small sanding block.
If the ink removal requires you to manipulate the sandpaper more carefully than a small sanding block or your fingers will allow, cut off a small piece of the sandpaper and glue it to the eraser end of a pencil. If the ink mark is not a deeply ingrained mark and depending on the thickness of the paper, then it is possible to cleanly erase a pen mark from the paper.
The best technique is to when using the rubber to rub gently with a very light touch. Not all pen erasers are created equal and there is one eraser that stands out from the crowd.
Check Price and Reviews on Amazon. It looks like these claims are not without substance as the A sand eraser has a very impressive 4. I am a big fan of reviews that are from people who have forked out their hard-earned dollars to buy the product to use it themselves. When you read the reviews, most are positive about using the pen to remove ballpoint ink and colored pencil marks from card and paper.
There are a couple of negative reviews and they tend to be that they have worn through the paper. It also turns out that this eraser is a huge hit with crafters for removing watercolor, glue and ink smudges and recommended on YouTube by Jennifer McGuire in one of her crafty videos. Using a rubber or sharp blade to remove ink from the paper is a technique that involves removing minute layers from the top surface of the paper and requires the ink to be not to deeply engrained, decent paper weight and a very light touch.
An alternative and very effective way of erasing the ink is by covering it up so that it can no longer be seen and writing over the top of it. This is backed up by a 4. Its correction fluid dries to a smooth seamless fluid unlike some of the brush type ones that look like white dried on cake mixture. To get the best performance out of the shake and squeeze wite out you need to give it a good shake to ensure that its fluid is mixed properly before applying it to the paper.
Ink erasers cost pennies now, but they are an ingenious piece of tech. Additional comments optional. You can offer your link to a page which is relevant to the topic of this post.
