On estate pipes, which have been well loved, I will ream them with either a decatur reamer or the senior reamer, then follow it with an appropriately sized dowel and sandpaper, 180 as the coursest, 320 most of the time.
On my daily workhorses, I tend to use the reamer on my pipe tool to gently scrape and smooth the cake, if it begins to get beyond a dime's thickness.
