Tips: It bleeds a natural dye so care must be taken when placing near existing surfaces i.e. concrete. To lessen the effects of the leaching, you can leave it out in several downpours. If staining has occurred, in the early stages, it can generally be removed by scrubbing with milk. Nail holes need to be pre-drilled as it splits when nailing but holds screws well.
