MYB chains – no problem. Muc Off, leave to soak, spin pedals backwards and scrub with a big brush. Hey presto – shiny chain.
The chain on my road bike though (maybe only 300 miles since new and lubed with Purple Extreme) has got a thin black coating of gunge on it, that is completely unaffected by the mucoff – hell it doesn't even come off on my fingers. I know from past experience that White Spirit will eventually shift it, but it takes a lot of scrubbing and gets everywhere in the process.
Is there a degreaser out there that "Just Works"(tm) (and ideally isn't too uneco friendly). (Oh, and I don't have easy access to petrol as my car is a diesel…)
