smudging is a traditional ceremonial practise, common to many first nations, which involves gathering herbs from the earth & burning them to purify a person or place. smudging is also used to connect to spirit and mother earth, as well as to summon ancestral spirits for help and guidance.

"spiritual house cleansing" is how you can define smoke cleansing. in other words, the smoke binds itself to harmful energy. as the smoke clears, it carries the harmful energy with it, discharging it into a new location where it is changed into beneficial energy. since smoke cleaning isn't tied to any one culture or religion, you can create your own rituals for you & your environment.
