You first get your materials and make sure you wear old clothes not new fancy clothes just encase you get wet or dirty, also wear old shoes not fancy shoes. Then you get your materials like a bucket of soapy water, paper towels, and a hose.
Afterwards, you vacuum inside the car and throw away any garbage, shortly after that scrub the outside of the car clean including the windows with the materials you got (the bucket of soapy water, paper towels, and ect.)
Finally, you can dry the car with paper towels or with towels, or the car can dry with the sun, your choice.Not only, dry the car but also put away your materials.
Then, your car would be shiny and clean and you won’t need to clean your car until like next month or the next two weeks.
