One of the first things a new mobile car wash or auto detailing business owner asks themselves is where do I purchase my supplies? It is important to use commercial grad automotive waxes, polishes and conditioners, not off the shelf stuff at Wal-Mart. Remember just because it is the same brand name does not mean that it is the same stuff. Most major automotive car care product suppliers have two different product lines. One which they sell to the big box store merchandisers and one which is sold through dealers or licensees, they typically are not the same. Although occasionally you will find a few items that are sold using each method, which are the same.
If you are running multiple crews and you have hired operators for your crews which have any longevity in the business you will find that they probably already have a preference for a certain brand of products and thus it would be wise for you to allow them to use such a brand. You may find that some use inferior products, which gives your customers an imperfect job, thus you may wish to check each product they use and approve it or disapprove it.
Owners of mobile carwash companies with multiple crews should allow each crew to purchase the supplies they need to complete their assigned routes and enough on hand to take walk up customers, well that is if there is actually time to take on additional clients, as the routes should be packed for maximum efficiency. If you are looking for business off your normal schedule, then you are wasting time, by assigning sales duties to auto care professional practitioners and technicians, which should be out making you money. Think on this.
