I've had my 2011 wee since January and used it regularly, despite my best efforts to keep it clean, some of the road salt has eventually got to the chain and the outer links are showing some rust on the outside faces. I have a scottoiler fitted and the inner links / 0-rings look nicely lubed, so it's really just cosmetic.
However, coming into spring I'd like to sort it out. So, what's your preferred method / product for getting rid of rust and restoring the chain to its former glory?
