This is important because if you soak the whole print head in liquid, the liquid will get inside the print head and you will burn or damage your print head the moment you plug it on.

Cleaning TIP

Another good way to clean the nozzle with more effectiveness is by using those ultrasonic cleaning devices you use for glasses. They cost around $20-$30 and can do a great job cleaning it with more success.


Never use harsh chemicals to clean your print head. Always use products that are meant to be used for cleaning the print head. No alcohol, Windex, Glass cleaner, or Acetone. Those products are corrosive and can damage the delicate parts of your print head.
