Since about 10 days I wipe the nozzle with non-stick silicon oil prior to printing, and then again after each print. I use the sort of silicon oil that is also used for easier release of castings from a mould. Since then I have no more build-up of molten material under the nozzle. Maybe you could try that?
First clean the nozzle's outside thoroughly: warm it up a bit (to 120°C or 150°C or so) and wipe it clean with a tissue. Then spray silicone oil on a small paper tissue (but do this far away from the printer, so that you get no oil on the build platform, which would destroy sticking). And wipe the nozzle with that tissue. After a print, immediately clean the nozzle and wipe it again with oil.
Apart from the brown spots I think your models come out quite nice, regarding those small details. Reducing temperature might also reduce the amount of brown goo, but that could also reduce layer bonding, so that might not be a good idea.
What interesting is ... when I printed with PLA I have had no such problems. Also I will change my hot end soon /( to E3D V6 ) and additional I bought a Silicone Sock for it
may be it will also help?
