My hack/commute/general bike doesn't get much love. It's got to the stage that even my bike degreaser isn't going to clean the chain/chainring/cassette. There's a thick layer of greasy dirty residue that won't budge, even with scrubbing with a toothbruch.
Methinks I need something a little more potent.
Before I go raiding my lab for chemicals, anything out there that will dissolve away this goo? I used to use Gunk on my old bikes when I was a kid, it's pretty much dissolve anything, but alas, that was the early 80's and there were fewer chemicals on the banned list back then...
recommendations (that doesn't involve diesel or petrol)?
