Note. I dont have Ender 3, I use a Prusa direct nozzle.
235 for PLA is excessive temp, at 40mm/sec speed Ill run 195 DegC, increased to 205 if I push ip to 75mm/sec.
Drop the temp to 205 or 210 and work down in increments of 5 until your print still has that glossy look.
The second part is over extrusion. Your printer may be pushing too much filament and so its a mess but start with temp and see how it cleans up. If you haven't yet done a filament test then do that too. There are plenty of how to's on the web about feed rate. I believe the Bowden style print heads do need a slightly higher temp and more feed pressure but I dont own one, so cant make judgement.
