The term "car wash" refers to a facility or business where vehicles are cleaned using water, soap and brushes. The process typically involves driving your car through an automated system that sprays water and soap at high pressure to remove dirt and grime from the exterior of the vehicle. In some cases, additional services such as waxing, polishing or vacuuming may also be offered.
The phrase "car wash" can also refer to a fundraising event where people wash cars for charity, or it can describe the act of cleaning your own car using a bucket, sponge and hose at home.
