How to Restore Diamond Plate Aluminum

[Connor]

My trailer floor looks like crap, it is aluminum diamond plate. I have thought about cleaning it but sounds like a pain in the A$$. Has anyone else done this? This site talks about using phosphoric acid.

mild aluminum brightner should do the trick

To Brighten Aluminum I have always used Coil Cleaner .. I use it on badly stained Alum. Filters and it brings back the shine .. Dont use Caustic or it will turn it white..

Where could I buy either of those locally???

If you are trying to clean your aluminum and maintian a shine that will show a reflection, don't use any hydro fluoric acid solutions or concentrated phosphoric for that matter. They will clean the aluminum but will dull out the shine as well. I would use a diluted citric acid cleaner if you are concerned about the finnish. If you are not concerned, use HF aluminum brightener.

Depending on the condition you may need a more aggressive cleaner like an HF or Phosphoric. If the tarnish is light a citric is a good choice or a diluted phosphoric. If you need to restore it when you are done you can polish it with a product like "mothers" and a buffing pad to bring back the mirror finish.
