My fiance works in a restaraunt and does the deep fryer and well I was wondering how to get those Oil stains out of his shirt. I have tried taking it as soon as he comes in and takes the shirt off and put in Hot water and let it soak I have even put Dawn dishwash and rubbed it in and let it set this rinse in hot water! I have even used Hot boiling water it got some out but not all! Is there a way to get it out?
