[Histonet] ink on film coverslips

[Amy Farnan]

Hi everyone,
I am trying to completely remove the dotting ink from our slides. I have tried alcohol and it takes off the blue dotting ink but the green ink leaves a yellow faded dot on the cover slip. The cover slips that we use are the film coverslip so I think the ink gets absorbed somehow. Do you have any ideas that may take the ink off of the cover slips? 
I would like to avoid taking the coverslip off the slide if possible.
 
Thank you,
Amy Farnan
