We use a 2 bucket wash system so that our wash mitts displace any grime into a clean bucket of water, and not back into the soap bucket. This lessens the chance of swirls and scratches from the wash process.
We strive to remove as much dirt and debris as possible during the vacuuming process. Carpet brushes and compressed air are normally used to remove debris and dirt from those hard to reach places.
Cup holders, center console, dashboard and windows are some of the interior areas we pay close attention to. These are some of the interior areas that need to be cleaned regularly. The Car Wash Basics speak for themselves.
