My absolute favorite way to clear energy out of a space is to first clean (mop) with Florida Water and then smudge with Palo Santo to further clear and charge the space.
You will receive 3 sticks of Palo Santo. The average set weighs in right around 1.5 ounces and they are approximately 3-5" long. They are hand split and therefore pretty uneven but oh so beautiful and are ethically sourced.
