I have a new chain and cassette and been using them for a couple of months now.
The chain and cassette get filthy pretty soon after a clean and I'm finding it a pain to clean the chain properly. I can get the cassette nice and shiney with an old pain brush and Gunk (a degreaser) but the chain is a pain to clean even when I give it a good going over with the Gunk and brush.
Does anyone have any tips for getting the chain clean? Do these sort of cleaning tools really work? I've never used one and have always been sceptical. I used a rag to try and get most of the worst off at the weekend but the chain is still black.
