My 4" cast iron stack in the basement (the vertical part/horizontal is fine) has a rusty bloom on it. Is there a treatment/preparation that will arrest that? TIA, RJ

Cast iron is sort of funny in that the rust you see might be purely external, while the interior of the soil pipe is fine. It's also funny in that it might just be rusty there, while the rest of the pipe is like new. On the other hand, the whole thing might be ready to explode.
You can leave it alone, or you could scrape it flat and cover it with a little epoxy putty.
