If you want to cleans your space burn sage or other cleansing herbs. If you want to cleans yourself an uncrossing bath might be better. Add sea salt, lemon juice and bay leafs to a bath and completely submerge yourself in it. When you get out of the bath if possible allow yourself to dry naturally.
White sage is an herb commonly used in purification/protection to help cleanse the area of negative spirits. Sage is also good for protection, along with Basil. So it will definitely cleanse you, and the space you have smudged.
