If a graphite pencil cannot be erased, is there a way to erase it?
Yes, the only method of erasing graphite pencils is through polishing with a chemical polish. This cleaning process can be done on an ordinary polisher, which does not have a polishing function. You would need to use a polishing tool, such as a polishing compound or paste, which would then be absorbed by the pencil and then wiped away by rubbing (e.g., when stroking). This cleaning process also does not have the ability to erase the pencil. Any solution to ensure that the pencil cannot be erased, such as acetone or alcohol, must be applied prior to polishing. The use of a chemical polish does not work well, because it can only clean up the surface of the pencil, it cannot remove the entire graphite. If there is an easy and inexpensive solution, such as acrylic or graphite cleaners, this will erase the pencil in a short time, and may be helpful in cleaning up the residual graphite.
What should you do if you cannot remove the graphite?
First, make sure that the pencil you have has been kept in a cool, dry room. Remove it from the pencil case first, and then place it in the refrigerator for a minimum of 24 hours. Then, place it, and your other pencils, in a plastic bag for 1 hour at room temperature. After 24 hours has passed, remove your pencils from the refrigerator. It is important to repeat this step every 24 hours or more if you want to ensure the remaining graphite is not removed.
Where should you dispose of graphite that has been removed due to the neglect of the pencil or its owner?
If your pencil has been left unopened in a place where there is no direct air circulation or where the temperature is too high (exceeding 85°F), it may be placed in a place where it will remain for a considerable amount of time. If your pencil has been left in contact with oxygen (such as if it has been in the air conditioning unit or heat up box), it may be destroyed beyond recoverability. In some cases, we recommend recycling the graphite, as it is less likely to be destroyed. This will not harm the graphite itself, but will remove the remaining graphite from the pencil.
Is there any evidence that suggests that graphite will permanently fade?
There are several studies that prove
