Provided is a method for cleaning a wafer that enables sufficient removal of cutting chips from the wafer surface. The method for cleaning a wafer includes: mounting a wafer 56 on a spinner table 4 such that a rear surface of the wafer 56 faces the spinner table 4 and a front surface 56a of the wafer 56 is exposed, the spinner table 4 being rotatable while holding the wafer 56; subjecting the front surface 56a of the wafer 56 to first cleaning with cleaning water supplied to the front surface 56a of the wafer 56, while rotating the spinner table 4; and subjecting the front surface 56a of the wafer 56 to second cleaning with ammonia water supplied to the front surface 56a of the wafer 56 using a brush.
