Cleaning is a non-canon, game-original Quirk carried by the villain Zookeeper. Her body secretes something close to dish soap, and brushing it across another person weakens or shuts down their Quirk. The same substance doubles as a cleanup tool, wiping crime scenes free of blood and prints.
Cleaning is an Emitter Quirk of close reach, used by the villain Zookeeper. It comes from game material rather than the manga or the anime, which places it among the series' non-canon powers.
Zookeeper produces a fluid resembling dish soap out of her own body. Applying it to a target, described as brushing or cleaning them, blunts that target's Quirk and can suppress it outright.
The secretion has a mundane use alongside the combat one. She scours away blood stains and fingerprints with it, erasing physical evidence from a scene.
Two named Ultimate Moves accompany the Quirk: All Cleaning and Cleaning Time.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
The Cleaning Quirk does not belong to a hero. It belongs to Zookeeper, a villain in My Hero Academia whose body produces a dish soap like fluid that can weaken or shut down another person's Quirk.
Cleaning lets its user, Zookeeper, secrete a substance similar to dish soap from her own body. Brushing it onto a target weakens or suppresses that person's Quirk, and the same fluid can wipe away blood and fingerprints.
No. Cleaning is a non canon, game original Quirk that appears outside the manga and anime, used exclusively by the villain Zookeeper.
Zookeeper's Cleaning Quirk has two named Ultimate Moves, All Cleaning and Cleaning Time.
Cleaning is classified as an Emitter Quirk that only works at close range, meaning Zookeeper must be near a target to weaken their Quirk.
