cleaning aluminum hull

[fishaholic82]

I've decided I need to clean my aluminum bay boat. Since I'll be at work for the next 4 weeks I figured I'd do some research to find the best product and ways to go about getting my boat looking better. I've heard about using the acid cleaners and if I go that route do I need to take extra precaution to keep the cleaner off the spray in liner that the inside of the boat is coated with.Do you guys have any tips or products that work well or even products to stay away from. Any help with this will be greatly appreciated. Thanks once I get it cleaned I'll post up some before and after shots of the boat.
