JEANS STAIN

I was on my way out of the mall when I noticed a black stain on my jeans. I thought it was from the ketchup of the siopao that I ate but it was black. Immediately I recalled I placed an uncapped pen in my pocket. When I got home, I placed my jeans in the washing machine and started the engine to roll. I even brushed the stain area but no good result at all. The stain is now permanently part of my Dickies jeans. There is still hope for me to remove this stain caused by the ball pen. I will use chlorine stain remover, color safe, in my jeans. I guess this will do the trick.
