Avoid dipping the lint into any cleaning solution as it deteriorates the quality and condition of the lint over time. Protect brushes from direct sunlight and LED lamp rays. Avoid applying excessive pressure on the brush, do not wipe lint with a cloth, just dab gently. Do not trim the lint "to the root"; if necessary, leave a few millimeters near the base.
