Muddy, Wet them down turn them inside out. Get a burlap bag and put about 15 round rocks the size of potatoes in the bag with the wet coveralls and roll them back and fourth on a side walk or porch. This will a stone wash them and quiet them down. Also leave them inside out and dry them in the hot summer sun.
Hope this helps it worked for me. You might do this cycle two to three times.
