I always give it a good scrub first with good old fashioned sunlight soap block and piping hot water, before I try soaking in Vanish. In my experience it works better.

Thank you I’ll give it a try.

Have you tried the product Vanish? It comes in a powder form to soak clothes in and also a spray form. I suggest you buy both. Spray the stain and let sit for recommended time. Mix up a bucket and soak your shirt for 24 hours then wash it. Stain should have at least faded. Repeat as necessary. Good luck
