Unfortunately I have a bit of a mess on my hands after having a filament leak from my Lite6 that resulted in a heater block covered in PLA. Are there any know ways to dissolve PLA out of the threads. With my crappy knock off hotend would jam I would heat it with the propane torch and burn it out but would rather not do that with the E3d. I believe it is stainless steel so the heat wouldn't mess with the metal too much.
