Recover the tip of your used brushes and leave them brand new. Water-soluble and not stain. Semi-transparent colour. Used at the end of the brush productions to give them the final touch.
Wet the tip of the brush on the gel, forming it with your fingers, and let it dry for about 10 minutes. Before repainting, wipe the tip of the brush a bit in with water to soften it. Repeat the process after each painting session and your brushes will be always like new
