New to bikes myself, so someone will no doubt correct me, but assuming the paint finishes are the same as cars. Never ever use fairy liquid or any other washing up liquids on your paintwork - the chemicals in them will ruin the finish. Hose down with cold water, use a good quality car shampoo and rinse with cold water again - cold water will neutralise any road salt. Hot water will disolve the salt and drive it deeper into those nooks n crannies. After its been washed down spray / wipe everything down with something like ACF-50 which should keep the corrosion at bay. Chain should be cleaned and lubed regularly too. Stewart
