You'll need
- Brass brush
- Heat-resistant gloves
Preheat to 220 °C
From the screen: Devices → Temperature → set the nozzle to 220 °C. Soft plastic comes off; hardened plastic just smears.
Brush gently, sideways
Glove on. Use the brass brush across the tip in short strokes — never poke straight at it.
Why this mattersBrass is softer than the hardened steel nozzle, so it won't scratch it.Inspect the silicone sock
Look for tears or carbonised lumps. A torn sock = bad temperature stability. Replace it if anything looks ragged.
Pro tipKeep two spare socks in your spares drawer. They cost less than a coffee.
