Does anyone have any clever ideas how to clean the burnt on oil stains and dribbled Wellseal stains from the fins and other difficult to get at parts of the engine. I've tried 'engine cleaner' from the local car accessories shop. I did improve the engine but wouldn't touch the tougher stains.
Attached is a picture before I started cleaning.
