Restore Eames Aluminium Group Chair / Base  

I'm not sure if the bases were lacquered on later editions or if you are in the US or not, but I'd discourage using power tools and instead try a quality cream-style metal polish like Flitz or a wadding-style like Duraglit or Ouator by hand on a small, inconspicuous area first. You might be surprised by results.

It takes a long time for high-polished aluminum to oxidize to a dull gray patina. I consider it evidence of authentic age and would prefer it to remain. Are you sure you want to pair gleaming metal with worn vinyl upholstery? I get that these are not museum pieces and that tarting them up won't deprive future generations in any way, but I will never understand furnishing a home with vintage pieces made to appear as new.

To clarify my previous post, polishing the aluminum bits is easily accomplished with nothing more than an appropriate polishing compound and old-fashion elbow grease. However, as a long-time Eames fan, I think your chairs look pretty great as pictured. If they were mine, a good rubdown with a soft cloth and a dilute solution of mild dish detergent and water is all they'd ever see.

Welcome to the forum.

Totally agree with you @tktoo2,

I am just going to clean them up a bit   and that would be it.

I can be obsessed sometimes with fixing stuff/restoring but I don’t think it is necessary or smart this time.

For the soft pad what would you do? Trying to give it New like feel... photo attached 

Thanks for all the advices.

I like Lexol products (cleaner/conditioner) for leather, but any established high-end boot maker/saddler should be able to recommend or supply safe, proven products available in your area.

Ah, now I can see that your Soft Pad is in dire need of ...absolutely nothing more than another decade's wear.

It's furniture, meltik.  Use it!

haha all right! Will do sir... thanks for the help.

To clarify my preceding put up, polishing the aluminum bits is effortlessly completed with not anything extra than the ideal polishing compound and antique-style elbow grease. However, as an extended-time Eames fan, I think your chairs look pretty exceptional as pictured you can see here. If they had been mine, an excellent rubdown with a soft material and a dilute answer of mild dish detergent and water is all they'd ever see.
