outriggers
I agree wash them every trip out, used or not....but I also put on a coat of woody's every couple of months. I actually attempt to to the T-top, bow rail, anything metal. It takes some time, but gives the Aluminum a nice shine after its done. But, note it doesn't last very long thus the repeat process. If you don't like Woody's there are plenty of other choices, I think GW gives you some with a new boat purchase (starts with Z, just can't recall the name) and I use that also, does about the same. Overall, a good cleaning after using is the most important aspect to long life......
