This article outlines an innovative solution for clearing detergent solutions after car washing. Managerial decision-making process being environmentally friendly is based on experimental data. The focus of the research is the development of a mobile car wash and dryer with regeneration of detergent solutions, which ensures environmental safety. The calculation of the prevented damage from the discharge of detergent solutions after car washing into water bodies was carried out as a result of an effective environmental solution. The economic efficiency of the proposed introduction of a mobile car wash with the regeneration of detergent solutions is given.

Toxicological assessment of waste detergent solutions were carried out to determine the hazardous degree of these solutions. The results of this assessment showed that even a significant dilution of the waste detergent solutions does not guarantee their environmental safety.
