My uncle kept in in a topdrawer.
One day I had to fetch the ink and when taking the bottle out of the drawer it turned out the lid wasn't closed well.
A few drops fell on my new dress.
I feared the anger of my mother and went to the kitchen and poured milk on my dress, put kitchen paper to absorb the coloured milk and repeated it often until the stains were gone.
When I came home my mom asked me what smelled so sour. LOL!
Some people use alcohol to remove ink stains.
On some surfaces and fabric bleach will do too.
