okay but not worth the money or shipping costs
I used to clean a heavy cast iron propane grill grate after cooking, don't use before cooking unless you wipe down the grate. Did the job, but as previous reviewer mentioned after few uses leaves flakes of the steel material on the grate, but takes off caked on grease and charred flesh from previous grilling.It's okay, but I will not be buying replacement scrubbers, the wire brushes do the same trick and don't leave any steel flakes in your grill.
