A "miswak" should be one hand span in length when selected. If it becomes dry, it should be soaked in water to soften the end bristles. The end should be cut afresh to ensure hygiene and should never be stored near a toilet or sink. The brush may be created by cutting "Salvadora persica"'s branches instead of its roots; keep in mind that the tree's roots can retain moisture more so than its branches. This favors more long-term usage.
