Fill the pan with enough water to cover the loofah completely. Bring the water to a boil before adding the loofah.
Drop the loofah into the boiling water using tongs.
Push the loofah under the water until it is fully submerged. Allowing the loofah to move freely prevents it from contacting the sides of the pan and burning. Leave the loofah in the boiling water for five minutes.
Remove the loofah from the boiling water using tongs. Shake off the excess water and place the loofah on a drying rack until it is completely dry.
