For the best results follow these simple instructions

• Fill the cup half full with water, add the cleaner concentrate
• Place the disassembled pen parts in the basket and screw shut
• Turn the unit over causing the cleaning solution to rise through the pen parts, for thorough cleaning of the most stubborn ink residues
• Leave to soak and then rinse thoroughly (cleaning time depends on how dirty the pens are)
• 10 sachets of concentrate with each unit
