I foolishly purchased a mostly light-grey textile biking jacket. Over time it has collected a good coating of traffic film and insects and when comparing the front with the back the difference is quite silly.
Any tips on what I can try and clean it with? Strongest thing I could find under the sink was cillit bang "grease and sparkle turbo foam" and that didn't touch it even slightly!
I've got some muc-off in the garage, might try that next lol.
