I have a White T shirt that has a lot of dirty splashes on the front of it. I have washed it a few times, vanished it, soaked it in detergent and let it dry in the sun but these splash marks haven't budged.
I have no idea what this stuff is as I don't recall them on it. Could it have come from the washing machine and if so how do I get rid if it both from the t shirt and the washer. Have tried a 90 degree wash cycle.
