Advice on cleaning a leaking nozzle

Discussion

Hi everyone !

So I've recently noticed black spots in a few prints. I checked if my nozzle was leaking and it turns out that it does. Since I have a silicone sock, I didn't noticed it for a while and there is a bit of buildup on the heater block and in the threads.

Do you guys have any advice when it comes to cleaning and especially cleaning threads ?

Edit : to add context, I have an E3D V6 on an Ender 5 and I'm cleaning PLA

Thx for your help ! I'm gonna look for a thin wire brush to clean that. Do you clean it with the heater block hot ?

Sorry, english is not my first language so just to be sure, wire brush are brush with metal wire only ? One with nylon wire would not work, right ?

If you have big blobs of filament, try peeling them off while the heater block is at around 100C. This will make your life easier as it's most likely gonna remove them in one piece.

If you don't find a wire brush, I had pretty good results with eco Q tips (the ones that have the stick made out of paper instead of plastic). Just make sure no cotton is left inside when you're done.

Yeah, no big blob, just a small one ;-) I still cleaned most of it @200°c

I was also thinking of Q tips but I was worried of cotton staying inside. I ended up buying a wire brush on amazon.fr but I'm not sure about the diameter, I just hope it'll fit.

Personally I don't find the plastic in the threads that problematic.. If it could flow out during regular printing, it will definitely flow out at higher temperatures when you're properly tightening the nozzle. Just make sure you clean any excess that flows out afterwards.
