If you leave ink on a brush, it will harden and damage the bristles. So make sure to wash your brush with water after use. Unlike some other kinds of paint, no special chemicals or solvents are necessary.
Let me show you how to wash your brush in a way that will make it last longer.

Why Brush Bristles Split — and How to Prevent It


Remember, calligraphy ink is permanent. When you wash your brush, it can stain the sink too, so avoid white surfaces like porcelain. A stainless steel kitchen sink should be easier to clean. Either way, make sure to clean up the sink when you’re done.
Once you’ve finished rinsing, shape the bristles into a point and hang the brush to dry in a well-ventilated, shaded area.
Only wash after you’re completely finished writing. If you want to take a break during your calligraphy session and continue later, I recommend wrapping the brush tip in plastic wrap.
