CarWash.HK is a platform that pairs up car-washing and automotive beauty service providers with their customers. We apply the new generation “waterless car-washing" method, which significantly reduces the limitations of traditional car washing and is suitable for using in door-to-door car washing services. We work with social welfare organisations to hire retired senior citizens and housewives and provide them with professional training. People who have completed the training programme can become a crew member of CarWash.HK and are able to take up door-to-door car washing jobs according to their preferred time and location.
