I say people just need to inspect their grill after using a wire brush.
30+ years and haven't had anyone eat a bristle yet.

First time I used a brass brush, I thought "Ewwwww! Now all that grease is trapped in the brush till the next time I bbq, then I can add more!"

After getting a few bristles in my fingers and thinking "hey, I wonder what swallowing one would be like?", I went back to the extreme heat method. I tried chemicals a couple times, but they are too messy. And what if you miss some on the racks? And there was always a funny smell the next time the BBQ got heated up.
Pressure washing might be a good idea too. But a tiger torch hears the whole BBQ up and cleans everything all at once. Rocks, burners - all of it.
Kiss it with the purifying flame!!
