Propagations of ion-acoustic dressed solitons in an unmagnetized dusty plasma consisting of a mixture of hot nonisothermal electrons, warm ions, and high negatively charged warm dust particles have been investigated. The reductive perturbation theory has been employed. At the lowest order of the perturbation theory a modified Korteweg–de Vries equation is obtained. At the next order of the perturbation theory, a linear inhomogeneous equation is obtained. Using the renormalization procedure introduced by Kodama and Taniuti, a stationary solution of the coupled equations has been obtained.
