Removal of oxidation from aluminum patio furniture

2004

I am a homeowner that has purchased new aluminum patio furniture. It has oxidized, very badly and quickly. How or who can someone recommend a product that may help remove the oxidation?

Aluminum per se is not corrosion resistant. If untreated, it quickly forms those white, salty-looking corrosion spots and streaks. What prevents that from happening is that either a clearcoat was applied at the factory, or anodization was done at the factory. When these treatments are not heavy enough to stop corrosion for long enough, you are left with the situation you have.

I have tried two different brands of aluminum cleaners from hardware stores and found them basically worthless. But if you are willing to try elbow grease, many readers here have recommended Mothers Polish for aluminum wheels and motorcycle frames, and you might want to try and see how that works for you. Although, frankly, most people aren't willing to spend as much time working on their patio furniture as their motorcycle :-)

You can use 25 gm sodium carbonate / washing soda [affil link]/25 gm water glass/1 lit water solution!

Good luck!
