Dust acoustic solitary waves are studied in a four-component dusty plasma. Positively and negatively charged mobile dust and Boltzmann-distributed electrons are considered. The ion distribution is taken as nonthermal. The Korteweg-de Vries equation is derived using reductive perturbation technique. We are able to reproduce the results obtained by Sayed and Mamun [Phys. Plasmas 14, 014501 (2007)] provided the Boltzmann distribution is considered for the ions. Higher order inhomogeneous differential equation is obtained for the dressed soliton. By using the renormalization method of Kodama and Taniuti [J. Phys. Soc. Jpn. 45, 298 (1978)], we derived the expression for the dressed soliton.
