The contrary could happen with too high temperature, lubricants migrate all over the caliber?
But who knows, a small fraction of lubicrants might migrate back to completely dry caliber locations yielding to a temporary improvement. For this to happen many properties would play a role, including temperature and duration, caliber geometry, physical prooerties of the lubricants and many more. Tribology is a very complex physics topic.

While I’m not advocating this “hot water” approach to dealing with a slow 32xxx movement, I do wonder if the apparent “fix” will be long term or short term.
And why are 32xx movements plagued with this issue?
