Clean has little in the way of offensive potential, doing little damage and having an extremely short range, similar to the immensely-powerful Hammer. However, the Clean ability is needed for many of the game's Heart Stars and can be very useful when paired with an Animal Friend. The ability focuses on different methods of cleaning, and its attacks with common household cleaning products. On his own, Kirby is only able to attack with a broom, but when used with an Animal Friend, he uses things like feather dusters, plungers and other such things. This ability also makes it the first time that the recurring enemy Broom Hatter gives an ability.
Clean is greatly improved upon and updated for its debut in the Kirby: Right Back at Ya!. He gains a yellow kerchief with green stars over his head, with a purple and yellow broom. The sparkles that shoot from it when swung can hurt enemies or cause any garbage and grime to magically disappear. Kirby can also sit on the broom and fly quickly through the air.
In the transformation sequence, the broom hits Kirby until he catches it, swings around and forms his kerchief.
