How to erase pen writing by chemical?

In summary, the conversation discusses the difficulty of erasing pen writing and the different methods available, such as liquid paper and sand rubber. However, these methods can be messy or damaging. The use of ferum tannate in blue pen ink is also mentioned, along with the question of what chemical can be used to discolour the ink. The conversation also brings up the possibility of using commercial products like Tipp-ex(R), which involves a white coating compound dissolved in trichloroethane to immobilize the compound on surfaces and allow for rewriting.

Pen is a common tool for writing, but it is difficult to erase them if errors occur.
There's some ways to erase the pen writing, such as liquid paper and sand rubber. However, using liquid paper is not really tidy, while sand rubber might make a hole in your paper! :smile:
I heard that blue pen ink contain ferum tannate, so what chemical can be used to discolour the ink?

Most ways will be messy since most methods are of liquid form. There are ways of removing such marks (even of permanent markers) if you had written them on a beaker...paper just won't do.

There are commercial products like Tipp-ex(R), in which a white coating compound is dissolved in trichloroethane, which is quite volatile to immobilize this compound on surfaces to where this preparation is applied. Then you can rewrite what you want after a short time.
 

1. Can any chemical erase pen writing?

No, not all chemicals can effectively erase pen writing. It depends on the type of ink used in the pen and the chemical's ability to break down or dissolve the ink.

2. What is the best chemical to use for erasing pen writing?

The best chemical to use for erasing pen writing is a solvent that is specifically designed to break down the type of ink used in the pen. Popular solvents include rubbing alcohol, nail polish remover, and bleach.

3. Is it safe to use chemicals to erase pen writing?

It is generally safe to use chemicals to erase pen writing, but caution should always be taken. Some chemicals can be harmful if ingested or come into contact with skin, so it is important to use gloves and work in a well-ventilated area.

4. How do I use chemicals to erase pen writing?

The method for using chemicals to erase pen writing may vary depending on the type of solvent used. Generally, you will want to apply the solvent to a cloth or cotton ball and gently rub it over the pen writing until it starts to fade. Then, wipe away the solvent and the ink should come off with it.

5. Can a chemical erase pen writing from any surface?

No, not all surfaces are compatible with chemical solvents. Some materials, such as delicate fabrics or certain types of paper, may be damaged by the use of chemicals. It is important to test the solvent on a small, inconspicuous area before attempting to erase pen writing on a larger area.
