Removing Mineral Stains from Aluminum Frames?

Safe/ One Restore barely touched the hard water staining on the glass or the frames. I just purchased a J Flint system from here on WCR to restore the glass. But is there anything else I can use to safely and effectively restore the brown aluminum window frames.

I really want the job. It is a large medical complex. And I believe that if I impress them with taking care of the stains, I have a good chance at getting the window cleaning of all the buildings.

Thanks for any help.

Is there anything in the WCR store that can effectively clean up metal frames from mineral spotting

Winsol offers a product called, Special Metals Cleaner but Its not going to take off mineral deposits, this is for grease and finger prints. Dave is right, Eaco Chem may have a product that could help. Sorry we don’t have something stronger for frames

[SIZE=3]Those brown aluminum frames are they older ones that eventually get oxidation on them?

Then when cleaning it actually take the brown coating off, after scrubbing?

Leaving bare aluminum spots on the frame?
