I have a edelbrock aluminum intake that was sitting around for a year and it has some fading with a little corrosion. What\'s a good cleaner or chemical I can use to clean it up?Bare aluminum surfaces tend to corrode and go dull when left exposed to the air. That\'s just the way things are. If you want. you could use a lot of elbow grease and a metal polishing compound like Simichrome to shine up your manifold, then spray it with clear-coat paint to help keep it bright. Just be sure that if you do use clear-coat paint, that it will stand up to the high temperatures of your engine compartment.I use Mother aluminum polish. It\'ll take a lot of patience and elbow grease but it works.Other related question
