10. Can we go to a car wash or just use the sprayer method by hand to wash the car ourselves?

It is recommended that the vehicle be washed by hand as often as possible. If you must use an automated car wash, look for a car wash that uses a touchless system, where only liquid contact with the paint. Never subject your vehicle to a wash system that uses harsh brushes or soft-scrub systems with cloth strips (sometimes called brushless) which can hold trapped dirt and debris that may scratch the finish of your vehicle.
