Had my first couple of proper Summer runs over the weekend due to an enforced time out ( me, not the three wheeler ). The engine is absolutely filthy, and covered in insects, oil and whatever else the road can throw at it. Understandably it isn't just washing off either.
Before I go at it hammer and tongs, I was wondering what tips, products or plain old do's or don'ts anyone out there is happy to impart before I inadvertently spoil the finish.
