Chosen Solution
I have a big stain on my running jacket from when I was biking & the sleeve got caught in my gears (it had snuck out of my pannier). I tried dish soap at first, which made no difference. Can’t specify if it’s grease or lube or dirt (or a combination); you know when you’re washing your bike & it just comes out all black? It’s like that. Any thoughts?
