Cartisan is an App based service, for different uses for cars. I have used their Eco Car Wash today. Very satisfied. It is door step service, @99 for hatchbacks. They don't use water, instead uses few 3M liquids and microfiber clothes. Also cleans interior with vacuum cleaner. Very satisfied with their service. This is excellent alternative to daily water car wash. Can be used once a week and monthly cost 400 or so is better and safer (with scratches) option. They took around 45 mins to do full cleaning. Going to use this for my car cleaning.
