how do you clean the metal tracks/trim of sliding shower doors?

[Lady Grey]

I've struggled with these in our house. Part of it, I am honestly aware, is a frequency issue. :yes I just can't figure out any easy (and natural) ways to get white spots off of the metal. Any tips?

Thanks.....

I just use a little borax on it. ;)

Peppermint Scrub recipe works pretty well on mine too. Thanks for the reminder to clean mine! ;)
