Plastic and Hot Coals . . . not a good combination
Spend a buck or two extra. Get a wood handled grill brush. I've gone the cheap way myself in the past and purchased these useless plastic handled grill brushes. First off, you can't put any reasonable amount of preasure on them to do any real grill cleaning... the handle will flex too much. Then, if you have to clean the grill, while it's HOT (like for something else after the first course)... your bristles are going to get all messed up. The bristles will sink into the slowly melting handle.more info
