I have just answer´d a similar Q. the best think for these marks is the good old fashioned washing soap, you can buy this in most hardware shops, and sure in some big super market´s . wet your garment rub the soap in to the stain , leave like this over night . then give a good rub ,rinse and hang out to dry . Normally you would do this when there is hot sun as the sun will bleach out the stain naturally
