Car Detailing Supplies

Hello I’m trying to get into portable car wash detailing. What are some good quality items to have in my itinerary to make the vehicles look professionally cleaned. (Pressure Washer, Carpet Extractor, Buffer, Sponges, Interior/ Exterior Brushes, Grit Guard Buckets & Microfibers, Generator, Hose Reels, Blower, Foam Canon, Water Supply System, any other Tools/ Machines that will help). Items that would help with deep cleaning, make vehicles look like show vehicles. Thanks in advance.
