what removes the black ink from a gel pen on cotton?

Question

straight bleach, shout, spray and wash stick, repeated washing and hairspray haven't worked.

Answer 1

Try Amodex spot remover.

Answer 2

Having tried all that you have, I found SOILOVE
made in the U.S.A. superior in laundry soil & stain removal.It's effective on Blood, Grease,
Ink, beverage, Food, Grass, Perspiration &
most other stains. America's Finest Products
Corporation is in Santa Monica, CA 90404

I first purchased it for over a dollar in markets
and find it stocked in 99 Cent Stores. You
must give it 2 minutes before adding it into
the washing machine or if hand washing.
Tip: I pour mine into a spray bottle.

Answer 3

try oops, goof off, or even wd 40 and dont machine dry until you are sure the stain is out.
