What to use to clean aluminim trailer?

[Gettin' There II]

I have a magic tilt dual axle aluminum trailer. I was wondering what does everyone use to clean (clean not polish) their aluminum trailer? I was considering using an aluminum wheel cleaner, spray on type product. I am a saltwater boater and rinse and wash the trailer after every use but it needs a little more now. Also while were at it is there way to get my galvanized wheels looking a little nicer. Thanks for your help.

I just use saltaway after every trip and when I washing the boat with soap and water I hit the trailer with the brush as well.
