STOK Cast Iron Grates On The Weber Performer

[ChaoSki]

I use this one for all of my cast iron, it's silicone I believe and it has a scraper (used it for years).

Lodge has a nice one for grills....I'm sure you can find longer handle ones too

Just don't use anything metal.....you just want something none metal/abrasive to prevent seasoning from coming off.

ChaoSki those look like fantastic suggestions! I knew about the Lodge example but not the OXO, which seems more suited to grills. I also see a newer version, less money: http://www.amazon.com/OXO-Grips-Electric-Grill-Panini/dp/B004ZLAGLS/ref=dp_ob_title_home

I'm thinking these kinds of brushes should also be "better" for regular nickel plated steel, which likely gets the nickel plating slowly scratched by wire bristles.

Yep

I love that brush for cast iron.  I find myself using it less and less as my Cast Iron skills/experience develops.....with my skillets I'm down to just wiping it with papertowel. Took some time to learn this skill hehe, but it's only possible with med/low heat cooking. Med/High is fine but High heat (like grill) and brush is needed for sure.
