To store paintbrushes properly means to store them so that the bristles do not become damaged or deformed. Brushes should not be stored resting against one another or so that any pressure is placed against the brush head.

One way to store paintbrushes so that they are out of harms way is to hang them from a rod on the ceiling. Install hooks onto rafters or floor joists, thread brushes through a wire rod and then hang the rod on the hooks. Ensure paintbrushes are dry when you store them so water does not drip onto the floor, creating a safety hazard.
