KOH-I-NOOR Rapidograph Pen System.. Cleaning?

Besides the Rapido-Eze Cleaner or Ultrasonic Cleaner, is there anything else I can use to clean my pens? Something around the house perhaps?

Also, is the Pressure-Bulb Cleaning Syringe absolutely needed?

The pressure bulb can be helpful, but it's not necessary.

Soak the pens in warm water to which you have added a bit of dish detergent and ammonia. Soak them until the wire and weight move when you shake them. (The ink is more soluble in a basic pH.)

If you are brave enough to take them apart, you can take the wire out and put it back in. That helps get the ink out of the tiny tube. However, if you bend the wire very much, you will have to buy a new nib.
