We get that one often!
A waterless car wash is a car wash that is done using high quality, concentrated product that have been engineered to produce the same washing value than a water-based car wash. They have the advantage to save tons of water for the same result. It also allow a detailer to perform a service in much more setup like very tight spots.
The only reason why you would not take a waterless wash is if you have extensive dirt (like dry mud) on your bodywork that is hard to remove without water. If you are not sure, just chat with us or call us.
If you want to know more, we wrote about it extensively in a blog post.
