how do you keep it clean? and turning a grayish white?

I have had aluminum intakes on small blocks and I have tried just about every thing I could think of to keep it clean, and in the process I have made some much worse. and the only thing that I could think of to do then was paint them.
if you do not run this in the rain or water puddles and keep it in a dry garage it will look fine they make rim cleaner that works very good to keep the cast aluminum looking good. it will not turn it white. my blower is harder to keep clean then my aluminum block water spots on the blower case .try never to get water on the blower when it hot or soap. i do not wash the engine evey time i wash the car i blow the car off with air if it get dusty water and soap is not that good for your car or truck any way. intakes get bad from water sitting on them and not dry them off but the block will not there is no place for the water to sit on it. the best thing to do is not put alot of junk on it spay cleaners and soap etc i have never did any thing to mine and it is four years old
