Step one: Hold your sponge/ blender under lukewarm running water for a few seconds. Squeeze it a few times to keep the water moving through it.
Step two: Squeeze your sponge/ blender one last time after you remove it from the water. Apply a dime size amount of soap.
Step three: Put the sponge/ blender back under running water. Keep squeezing it until the water is running clear underneath it.
Step four: Lay it out on a flat, clean towel. Leave it to dry for a couple of hours.
