Hey everybody, I was just wondering what I should do to keep my nozzle clean because after I used one for a while, I had to buy a new one because it got rusty and wouldn’t work. Feedback would be greatly appreciated!

hey, what do i do if my printer wont purge, and the last bit of filament (about 4 inches) is still stuck in there? pleaaase help, i am really stressed. btw i cant do a cold pull because i dont have one of those needles.
