Aluminum oxidizes and scratches easily, so polishing is a constant and
labor-intensive approach. And do you really want all that reflected
glare? Those with the "bristol" approach to aluminum care, clean it
well; then apply an appropriate dilute acid etch for the recommended
short timespan; followed by the recommended base stopper solution.
Follow directions and you'll have an easy care, uniform dull oxide-white
finish that wonderfully masks mineral deposit, scratches and dings. If
you're in salt water, use bottom paint below the waterline to fight off
the algae, etc. If you can't live without shine, paint the topsides
too. Good luck.

I am attempting to fix/clean-up a 24ft pontoon boat. I would like to
start out by cleaning up and polishing the aluminum. It has not been
cared for in quite a while. Is there any particular chemicals and
techniques that I should follow?

Thanks in advance for all your help.

God Bless!
