Wow Alvin, been around the metal working business since I was
a kid, worked for nearly three decades at an accelerator
that was built out of SS. I welded it for half of my time
served there, and In all those years, I never saw any SS that
would tarnish. I've seen SS trim that has sat in scrap yards
for half a century where the rest of the vehicle had rusted
away around it, and the SS still looked great and would only
take a wipe down with some chrome polish to take the grime
off.
Point is....are you sure it's SS?
