How do I clean my outerwear with a bike grime stain?
My running jacket has a big black stain on the sleeve from where it got caught in my gears on a bike trip (it slipped out of my pannier). I tried dish soap at first, which made no difference. I can’t describe if it’s chain lube or grease or dirt (probably some combination); you know when you clean your chain/bike & it’s all black & grimy? It’s like that.
