How do i get a mud stain of my jacket?

Question:its my favorite one, and detergent is'nt strong enough

Answers:
You could try a laundry pre-treater, like Spray and Wash; saturate the stain with it and let sit overnight if possible. Then spray it down again and run it through the washing machine.

If you've already washed and dried the jacket, the stain is likely set into the fabric, and it might be time to take it to a professional.
