The first part of space clearing is literally taking out the things in your home that do not serve you ( or your family) anymore. This should be done from time to time, to ensure your things can be easily found, and old energies do not stagnate.
Herbs and Incense like Palo Santo Wood, White Sage Clusters & Frankincense can be burned to purify the space. Essences & Sprays such as the White Sage Mist, Banish! Oil & Mist are very mobile and convenient to use. Another way is to diffuse Frankincense & Palo Santo Essential Oils daily to purify your space.
