I want to clean up my engine bay.

Whats the best way to tackle the Valve cover and the Fuel Rails. I want a clean engine bay but dont whant polished shiny valve covers etc. Also my fuel rails are stained, looks like rust but not sure, anyone tackled this?

Any tips on what to use to get things looking clean again?

Thanks.

I guess you could try some of the aluminum wheel cleaner. If you don't want a polished finish most of these have a mild acid that will clean them up pretty good, and it's easy too. Just spray it on and hose it off. It will leave a somewhat whitish color to the aluminum though.

I believe the fuel rail had some type of coating on it from the factory, perhaps some type of cadmium plating. It should come off using a cleaner. For the really tough parts you might try using a very fine scotch-brite pad.
