A Stick.

Haha. But seriously - for some reason I kept using a wire brush to clean my grill for too long after learning about how dangerous they can be.

And there’s no need to get fancy here. A little scrap stick of hardwood works great and is basically free if you do any woodworking or know anyone who does.

Stick to solid wood and don’t use anything pressure treated, painted/finished or glued like plywood.
