Is it ever possible to get black permanent marker out of pants?

I don't think so. If you wash it a lot it may fade a little. You may have to resort to bleach but that leaves marks and stuff and ruins the pants anyways.

We should also know the fabric, that would help. And these following ways are CRAZY with house hold objects, I haven't tried them myself but apparently they work.

Hairspray: Get the stain damp, then blot it away after spraying slightly with non oily hair spray. :)

Rubbing Alcohol: Put a paper towel on top of the stain. Blot alcohol on and you should see the stain lift onto the towel. Refresh towel regularly.

MILK!: Take a bowl of milk and dip the stain in. When the milk stops turning to the color of the stain, get a new bowl of milk and repeat until the milk stops turning color or only turns to a grey.

*Wash is recommended at the end of each set of directions.

Only chance is dab it with a papertowel soaked in rubbing alcohol. Then immediately rinse spot under cold water and put detergent on the spot and wash the pants.

I don't think so, the key word is "permanent". Maybe dye the pants black?

alcohol...
