Will making and reducing pork stock ruin my kettle for brewing?

Hello,
Was wondering this. A friend is having a party, making home made pork stock for some ramen, and wants to boil down 10 gallons to 5. He'll be using bones, meat, and fat. He's asked if he can borrow my equipment to do this, and I told him that would be ok as long as it wouldn't mess up my pot for brewing, which he totally understood.
The pot in question is an 19g stainless pot, with a SS weldless kit.
Is this something a good cleaning will take care of, or should I help find another solution? Thanks!

As long as nothing gets scorched onto the bottom of the pot, just clean it out and it'll be fine. Stainless won't hold any odors/flavors. We do crab boils in my brewpot!

I just boiled 40 ear of corn in my HLT. Just make sure it gets a good cleaning afterward.

Thanks for the replies. I'd love to be able to help him out, especially since I get to partake.

I fried a turkey in my turkey fryer/brew pot. Just clean it out!

And boiling pbw in high concentration will even take any black scorch marks off the bottom w/o issue. I'll boil shallow water and throw lots of pbw directly on the scorch marks and they typically come right out.

Yep. Big dose of PBW/Oxyclean after the turkey fry, and my pot was back to normal!
