Hey all, I figured if I can’t get these spots someone on the interwebs knows..

A few of my whites/lights have these dark grey spots that nothing will get out. I’ll post more pics when I find the others. I’ve tried most sprays, Oxyclean directly on it. I’ve tried lemon juice, hydro peroxide, not sure if did that AND put it in the sun yet… I don’t really know what caused them, I assume some food/sauce/oil of some type.

Let me know if you’ve come across this and what you did that worked! Cheers
