This research article proposes the application of Lean Total Quality Management (TQM) and Systematic Layout Planning (SLP) tools to review, standardize and improve the car wash process of a SME in Peru. With SLP an improvement in the distribution of the washing station is proposed. Within TQM, the PDCA cycle tools were applied to identify problems and the 5S methodology to have improvements within each activity. Under the simulation of the proposed model validated with the Arena software, an 11% increase in the station's productivity was achieved based on a 13% decrease in washing time as well as a 36% reduction in the number of lost customers due to waiting time in queues or dissatisfaction with the service, improving service efficiency and reducing reprocessing.
