    As the title. How to clean dirty, oil-stained and in some parts slightly whitened alloy engine castings? Is there a magic bullet without the vapour blasting technique? Some bits I simply can't take off the engine.

    Use aluminium cleaner available from trade cleaning suppliers.

    There is, nasty stuff, its called HF.
    Its found in various good ally cleaning products like Air conditioning coil cleaners and especially useful ally wheel cleaner. Make sure you wash it of well then spray ally with a sticky silicon lubricant regularly to stop it degrading again.
