A control method for a clothing treatment apparatus. The clothing treatment apparatus includes an air washing device for performing air washing on clothing. The control method includes: obtaining the material of clothing; obtaining the type of a clothing detergent; obtaining the type of a stain on the clothing; and determining a parametric range of air washing according to the material of the clothing, the type of the clothing detergent, and the type of the stain on the clothing. The embodiments allow clothing to be subjected to air washing treatment within an optical parametric range, i.e., a detergent can exert an activation function to the greatest extent, and also allows a stain to be removed and cleaned within the most suitable parametric range to improve the clothing decontamination capability, thereby improving a clothing treatment effect and improving user experience.
