Cleaning badly carbonized s/s pressure canner

[Lazy_Ant_Brewing]

My daughter was canning salsa in a S/S pressure cooker and apparently failed to add enough water.  The canner ran dry and carbonized some sugar present in the salsa.  It’s really burnt on!!.

I’m pondering having her put water in it, heat it up and pressurize it for a while to loosen the crud, and then go with a scouring pad and lots of elbow grease.  Thank goodness it wasn’t my brew pot.

Any one have any suggestions for cleaning?

Thanks in advance for your ideas.

PBW to remove first layer, run it hot at 180F.
For residual deposits Bar Keepers friend is the stuff, as Steve has said.

Had some scissors that got rusty, thick application of BKF and some scrubbing, and those are shiny new looking.

Yep, sounds like a plan. BKF rocks.
