Hi all. New to the Forum, but there does appear to be a lot of good info around here. Anyway onto my question. The rear sprocket on my Blade is a little bit spotty what I mean is that the previous owner had left it standing and the sprocket has a few white spots on it and I have given it a good scrub, but it will not shift. I have only had it for a couple of months and I want to sort it out so what would you recommend to get it off. I thought maybe a wire brush, but I do not want to be too rough.

All good ideas greatfully appreciated.

Use Castrol Super Clean and scrub lightly with a wire brush. You'll do no damage. The cleaner/degreaser will do the scrubbing for you. Look at the picture of it below.

Just be careful with it it will dull any polished alu.

Thanks guys for the advice and I will getting a bottle of that A.S.A.P.
