I've tried everything I can think of:
Soaking in Oxy-clean type powder
Same stuff poured on neat to damp collar
Stain digester soaked for 24 hours
Shout spray
Vanish stain remover bar
Sports wash
Biological washing liquid rubbed in and then machine washed
Is there a magical formula for getting the yellow grime out of gi collars?
