I bought some new stuff at the weekend. Muck off chain cleaner. Works a treat, spray some on all round the chain, leave for a couple mins then go back to it, spray some on the brush of your choice and brush away applying to wither chain or brush as you see fit, comes up spotless. Once all done then lubricate, and for this i got some wd40 chain lube. Ok not the cheapest of stuff but the chain lube is anti fling and seems to be great at lubing and not attracting grub, and the cleaner looks like i will be able to clean my chain another 5 or 6 times, so yes its £12 but works out about £2 a time which i can live with
