And here I was going to just throw my jacket away... I soaked it in dishwashing liquid for a couple of days and scrubbed the marks with a brush, which took out half of it. Then, I soaked it for another couple of days and now there are only two of the most severe marks, but they are lighter!

I also tried the simple green, which helped slightly, but Dawn was the biggest help. Thanks for all your suggestions!!!
