Thanks for the pinch hit, MacKenzie!
PBW is an oxygen based bleach and cleaner used in breweries (and by homebrewers, too) to clean equipment. It works really well on organics; hence, it works great on our stainless grills, roti baskets, drip pans, etc. that have accumulated some serious protein gunk. Readily found in the US at homebrewing supply shops/online retail. Think Oxyclean on steroids. Was actually developed by Coors. A tad pricey, but a little goes a long way (1 Tbl per gallon of water). Rinses off easily, too.
