I have an Andersen Ultimate 5th wheel hitch which uses a block of aluminum as part of the hitch.

We have been around the gulf coast for several week and I am noticing some corrosion on the aluminum.

1- what can I use to clean the aluminum
2-what can I use to seal the aluminum to stop further corrosion.

I have emailed the factory, but wanted to see what experiences you all have had.

Thanks.
