I recently obtained these Trico arms, which I'm told are correct for the 1970 Mach 1 or 1970 Mustang in general. If that is indeed the case, what is the best way to clean and/or polish them? I want them to look correct and clean, but don't want to change the finish to something that won't appear correct.
They seem to be at least partially stainless, but the part that attaches to the wiper blade does not attract a magnet, so maybe that part is aluminum?
If they are stainless, would it be okay to just use a stainless cleaner and/or polish on these?
Thanks for any info and suggestions!
