There's a huge difference in quality of the metal. I bought a stainless
steel grill that promptly rusted. It's ugly (and now covered), but I
have to admit it has lasted much longer then my other grills. I think
this one is going on 3 years, and most fall apart the same day that the
12 month warranty expires. The rust appears to be mostly cosmetic...

Acid, you say? Hm, I have a gallon in the garage to clean cement...
I'll give it a try.
