I've been using balls of crumpled up aluminum foil held with tongs. My father grills more often than I do and I bought him a dedicated tool for grill cleaning from a craft fair; it's a brass disk on a stick, with various grate profiles cut out of the disk. It works well, but is a little slower than some other tools. Looks like the creator has a web store now[1].

I like this idea but cleaning each little grill bar individually sounds too time consuming.
