Hi
I gave my bike a full clean yesterday . When going over the rim stripes (that red looks so much prettier being reflective again) the rear one chain side had some black sticky dirt on them. I suppose that's chain wax residu that won't come off. Tried bleach, tried scrubbing with dish soap. WD40 could cause decoloring I read - so I'm reluctant to making that rim stripe pink

How do you remove that dirt?
Cheers
