Cleansing

Cleansing is an status effect characterized by removing specific types of bloons and neutralizing them into less "dangerous" bloons. It is part of the damage types family.

Cleansing is represented on Bloons Wiki as, the upgrade portrait for Cleansing Foam, depicting the monkey's apparent eagerness for cleanliness, and because the upgrade's upgrade icon is not representative enough due to featuring just a Camo Bloon. Cleansing is not the same as Downgrade Layer because Downgrade Layer is often universal in what bloons are affected, and it's based mainly on damage. Cleansing is classified as a property-stripping status effect, as it is the removal of a specific bloon type, sort of like rubbing off dead skin flakes with soap but leaving the live skin intact.

An example of Cleansing is, to no surprise, Cleansing Foam. What makes the BTD6 Cleansing Foam considered "Cleansing" as opposite to Extra Damage to Leads is how its foam only ever damages non-DDT Lead Bloons by converting them into Black Bloons.

All attacks require an upgrade to apply Cleansing behavior.
