E3d Heater Block Cleaning

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.

I read somewhere that Chloroform dissolves PLA, same as Acetone does fro ABS.

Just remember, it is only to be used on PLA!

I sometimes run an m6 tap through a heaterblock to clean the threads.

I have used this stuff to loosen up and dissolve PLA. I let it soak for a few days and it does a pretty good job. Be sure to use proper safety procedures when using this stuff. I can be nasty. If I remember correctly, it is the Dichloromethane {Methylene chloride) that is a solvent for PLA.
