How it’s done:
There are different types of car washes available like Handwash, Automatic Car wash, Waterless Wash, and even Mobile Doorstep Car Wash.
If you have the time, Handwash is always the safest way to get it done. Typically, the mechanic starts with covering the exterior surfaces in which the vehicle is covered with foam and rinse the car off. From there, he washes the wheels and tyres.
Waterless Wash is a more eco-friendly option and typically it is done by using a water-based chemical like 3M Waterless Wash.
You can also opt for an Automatic Car Wash also known as tunnel washes. While they are not as safe as hand washing your car, they are less and expensive and take a lot less time.
