What you need:
1. Acetone
2. Torch (Available on eBay at around $5)

Step 1:
Soak the removed nozzle into acetone for about 15 minutes to clean out exterior dirt. Use a tissue paper/cloth wipe clean the nozzle.

Step 2:
Place a nozzle on a stone and burn it using the torch for about 1 min. Make sure it is extremely hot until you see slight changes in the colour.

Step 3:
Use a very thin wire to clear the hole in the nozzle. If the wire cannot go through repeat step 2 again until it can go through. Do not force through the hole with the wire. You do not want to scratch/damage the internal wall of the nozzle. I use soft copper wire stripped from an unused phone cable.

If everything goes well, the nozzle should extrude nice smooth thick filament.
