I have a Tracker that I love except for cleaning the aluminum hull. Does anyone have any suggestion as to what to use and where to get it.  Thanks

Local Wal/Mart Automotive dept. Greased Lighting Orange Blast; it'll clean any thing  

Got this off their website faq. Not sure I'd try it!! :-?

Can I use Greased Lightning Multipurpose on metals?

Greased Lightning products are recommended for use on most metals except aluminum or an aluminum alloy. Greased Lightning will leave a cloudy appearance on aluminum. However, this does not apply to aluminum siding with a factory baked-on finish.

Try BASS BOAT SAVER its a great product made for fiberglass but reps tell me that it works wonders on aluminum too hope this helps

Citric acid.  (sounds rough but it's very mild, makes aluminum SHINE)

Clean your boat with orange juice????
