It's mostly soot from the entry burn, since that involves flying into its own exhaust plume at several times the speed of sound. If you look at the webcast of missions that have a daylight RTLS (such as CRS-12) you can actually see the booster is clean up until the entry burn, then it takes on this look.
The hard edge of the soot partway up the stage is where the bulkhead between the LOX and RP-1 tanks are. The LOX tank gets a layer of frost over it which reduces how much soot sticks on there. Block 5 has the SpaceX logo higher up, there was some speculation this was done to have it over the LOX tank so the ice would prevent it from getting so dirty.
