PBW and scorched grain

[stosh]

Does PBW loosen or remove scorched grain from the bottom of a kettle?

I'll use good ole fashioned elbow grease too but I have multiple kettles to clean after our annual 20 gallon brew day and was hoping to get a leg up on them.

Yes, it will clean scorched wort off with minimal scrubbing. It leaves the electric element in my kettle like new with just a soak.

I have the best results with hot PBW followed by acid (I use citric acid 1 Tbsp/gal) with rinses before and after each step.
