Do GrillGrates cause your stainless grill grate to rust?

[GrillMeister]

When I had my old Brinkman gasser, I had grill grates sitting on the stainless grate all the time. I had 4 of them.

When I got my new small KitchenAid to replace it, I noticed the Brinkman stainless grates underneath the aluminum GrillGrates was rusted to *&#%.

Could this be from galvanic reaction between aluminum and steel?

I don't know, but since I use my new KitchenAid gasser for pretty much searing, when I am done, I slide some cedar planks under the GrillGrates as an insulator.

So far, so good on my stainless grates.

StainLESS does not mean rust PROOF..

Correct, since stainless comes in so many grades, some of which are 50/50 impure.

The combination of aluminum and stainless steel causes galvanic corrosion. In order to understand why you shouldn’t use stainless steel and aluminum together, we first need to understand how galvanic corrosion works.

So the moral of the story is Do Not Leave Your GrillGrates on your grill grates after use.
