If your filament doesn’t come out, heat up the nozzle more until you can pull it easily.
Avoid using any materials that have a lower melting point since they won’t retain their shape as well.
Always cut the dirty end off of the filament so you don’t put it back in your nozzle.
Wire brushes can be purchased from your local hardware store. Check the nozzle’s packaging to see if it’s safe to use a metal brush on it.
Removing a nozzle cold could damage the threads and make it more difficult to screw back on.
Don’t touch the nozzle with your bare hands or else you will get burned.
Acetone is commonly used as nail polish remover and can be purchased at your local drugstore. The acetone helps loosen the dirt and grime on the outside of your nozzle as well as breaks apart the filament inside.
Heat guns can be bought from hardware stores. Don’t point the heat gun directly at anyone since it could cause burns over time.
Wipe the wire or needles clean whenever there’s residue stuck on them.
