Could you not just mist with water?

Based on my knowledge of metallurgy, machining and gunsmithing (amateur).

I would advise against this.

There is also the wet rag/towel idea but same.

We're talking about cooling from something like 190F to ambient, and not that rapidly either. What metallurgical concerns do you have?
