how to remove black stains from clothes

I am seriously freaking out over these black stains on my favorite shirt. I had this amazing dinner last night, and apparently, the sauce loved my clothes way too much. I don’t know exactly what it was, but now there are these nasty black stains all over. I washed it right after, thinking it would help, but nope, not even a little! I’ve tried pre-treating the stains using regular detergent and then washing again, but still no luck. I even stumbled upon this really old trick using baking soda and vinegar, but that didn't seem to work either. I really don’t want to toss my shirt – it means a lot to me! Honestly, if anyone here could give me some tips on how to remove black stains from clothes, I'd be so grateful. Like, should I be using bleach or is that just gonna make it worse? Or are there any homemade remedies that actually work? I read somewhere that certain fabrics react differently, and I’m terrified of ruining my shirt even more. It’s honestly a bit frustrating! Anyway, how to remove black stains from clothes is all I can think about right now, and any advice would be super helpful! Thanks a million!
