Many new entrants into the mobile auto cleaning business want to save money on equipment and others have heard about Dry Wash, which does not require water; this is very good for drought ridden areas. Not long ago someone interested in getting into the business asks me: “Do you use a pressure washer in your business?”Yes, absolutely! Personally, I do not like Dry Wash or Dry wash’n Guard, or environmentally friendly (proclaimed) smear on dirt, wipe off type products. But its more than that, you see customers hate it when they see you use that stuff and it takes 2-3 times as long to clean the car, plus the cost is so much higher for these products.The PR problems with trying to explain this to customers, that you are not scratching their car with your smear product is a tough row to hoe! Go ahead and do this; search on Google: “Mobile Auto Detailing Business; Dry Wash or Pressure Wash” and this 1300 word article will go into far greater details.Now then for some things, I will admit the Dry Wash can be a superior method, for instance in parking structures cleaning high-end cars with very little dirt on them, just a layer of dust or cleaning corporate jets in Hangers, with floors so clean you could eat off of them. In this case, there is no sense in using water to rinse and dry. Why bother setting up a pressure washer, wasting water and spending hours drying off the wings and fuselage of a corporate jet? Please consider this.
