There are many aspects to eco friendly detailing that cxan be considered. beside the obvious water use reduction and waste elimination, one can consider all the aspects of there business when comtemplating eco friendlyness.
For example for a mobile detailer there is the aspect of being mobile that comes into play, are you hauling a large trailer around behing a full size truck, or are you carring only the supplies you need to get you through your day in a small vehicule. When going out to do an estimate do you take a small car, or do you haul your complete rig out. Scheduling is also important, do you schedule jobs in the same area on the same day, do you group together similar jobs, so that you will only need a small part of your tools and products? By reducing the quantity of products you carry you increase fuel milage, and reduce your carbon footprint.
For fixed locations, have you switched your lighting to more efficient lighting, have you installed a oil sepperator into your drain line, do you wiat to have a full ooad of towels before starting the wash, do you pre0rince outside, or do all your wet work inside so that the run-off goes through the proper channels? There are many more aspects to consider when thinking green.
Every aspect of your business, or home washing can be examined and the best available technologies used.
As an example, in many postings on this forum, and others, we see pictures of cars covered in foam, and drivways covered and even the street, that needs to change. Many postings deal with using ONR, but before using ONR the person goes on to post that they pre-rinse the car, and even some pre-wash with soap, others will use 2 buckets of water to wash with ONR. Take it from me all of that is wastefull. The product works as designed, meaning minimal water use, and no need to rinse. I run 7 shops , all use ONR all use 1 bucket, and all use the same bucket for several cars, and never have we had an issue with scratching, try it and you will see. Another very good option exists and that is watrerless washing, while it makes some cringe at just the thought(I used to be one of those) it does work, and works very well at that. Waterless thechnologioes have advanced to apoint that they not only clean, but offer outstanding protection for the paint once cleaned, before cringing try it.
So in resumé being eco is a thought process,and an awareness, the next time you do something think about your action, and how it will influence future generations . .
