Ink will come out with alcohol. Most food stains are fat soluble and can be removed with dish soap and water. Stains that can be removed with alcohol or dish soap will be set by an acid, like vinegar so remove the stains before removing the smell.

Don’t bother separating all your clothes by color. As long as you don’t have white T-shirts in there, the colors will be fine.
