If the interval between two pen uses does not cause the pen tip to dry and harden, there is no need to clean it every day.

Excessive pen washing will make the pen degreased, rough, dry and inelastic, and it is easy to break and lose hair.

However, if the pen is not washed for a long time, the ink glue will deposit at the root of the pen tip, which will not completely spread the pen tip, which will not only affect writing, but also lead to pen breakage.

Therefore, it is best to clean the brush that is often used once in a while. When cleaning, don't press it, swing it back and forth in clear water, without rinsing it with clear water, just wash off the glue inside and at the bottom of the pen tip, and then use waste rice paper and wool paper to absorb water along the pen tip.

If the interval is long, wash it every time.
