Removing ink stains is simple when you know how.

If you use printer ink cartridges, there will come a time when you have to deal with spilt ink and printer ink stains. 
Ink spills and stains can happen due to a leaking ink cartridge, or because of not handling ink cartridges correctly.
Either way, most ink stains can be dealt with effectively. If you do spill ink, it is best to get at the ink stain as quickly as possible.
If you get ink on your hands, you can try washing your hands with a very mild water and bleach solution, using just a tiny amount of bleach and then simply wash your hands again with soap and water and rinse. This should remove most of the ink. The stain should fade in a few days in any case, if you do not get rid of it through immediate washing.

If you get ink stains on your clothes, generally it is recommended that you wash the clothes in cold water, maybe presoaking them first with detergent, always in cold water.
If the ink-stained clothes are whites, you can also add a small amount of bleach as well. The cold water prevents the ink from setting into the fabric. The printer ink should come out in the wash.

One way to avoid spilling ink and creating a stain in the first place is to take precautions when you will be handling ink cartridges.
Use disposable gloves when handling printer ink cartridges.
Protect surfaces that you will be near when handling the cartridges by covering them, such as by putting paper on the floor for example. 
Advance preparation and being careful when handling ink and ink cartridges can prevent most ink spills from happening and make it easy to deal with them when they do.
