Cleaning diamond plate aluminum tool box

Have a 10 y/o Deflecta-Shield diamond plate aluminum truck tool box, uncoated, called Brite finish. Mostly dull and oxidized on top of the lid. Looking to clean it back to bright for cheap... meaning I really don't wanna spend another nickel on it so I'd prolly be using stuff off my shelf.... citric cleaners, wheel cleaners etc. I have some old wool bonnets I could polish it out w/ compound but nothing gonna be too labor intensive here... be listing on CL for about $75.

Anything in a spray n rinse that'll make it shine decently w/o polishing? It's only gotta be shiny for a week or two until it sells.

TIA

Polishing is the only thing that'll bring any shine back.

Pretty sure citrus cleaner will dull the heck out of the finish.

+1 polish with power tools then coat with oil.

D'oh! Missed that part...

I thought he wanted to get it done in less than five minutes.

I was hoping for some grassroots solution like mixing Kool-Aid powder and toilet bowl cleaner for a cheap show quality finish.

Guess it'll hafta be compound and bonnet.

It's goin' on CL anyway.... I'll ask $80, they'll offer $30.
