This thread caught my attention because I never heard of similar things here in Brazil (at least not in the south, where BBQ is a basic need)
Reasons:
1 - we use lifts (?): like this one [1]
2 - people, in general, clean the grill using some rough paper while the grill is still hot, then wash it with some sponge, water and soap.
Hardly something that has metal (like brass or steel brush) is used, since they affect the grill surface with small scratches that will accumulate more fat next time,in an endless loop.
