Don't use washing up liquid it's full of salt, any cheap car shampoo will do. If it's proper sticky grime then some WD40 on a rag and wipe it down first then shampoo it.Anyone got any cleaning tips? The bike has been off the road for 3.5 years so I've not done it in a while. It was reasonably clean but I've since been out in the rain and there is a layer of grime on the wheels and exhaust. Can I use washing up liquid or is car shampoo stuff better? I've got some Scottoiler anti-corrosion stuff so I'll put a layer of that on after.
