What should not be done to remove excess ink from the pen point?

Dipping the pen tip in an ammonia solution is not advisable for removing excess ink because ammonia can be a harsh chemical that may damage the delicate materials of the pen, such as the nib or the feed. Instead of effectively cleaning the ink, using an ammonia solution could lead to deterioration of the pen's components and affect its performance.

In contrast, methods like gently tapping the pen on a paper towel, blotting the tip with a cloth, and wiping the tip on a dry surface are safer practices. These methods absorb excess ink without risking damage to the pen, allowing it to function optimally without introducing harmful substances. It's crucial to maintain the integrity of the writing instrument during cleaning to ensure a smooth writing experience and preserve the pen's lifespan.
