Car Exterior Cleaning: Basic Detailing Procedures

  • Car Exterior Cleaning: Basic Detailing Procedures
    November 26, 2012

    If your idea of automotive detailing is a quick spin through the local car wash, followed by plopping 4-quarters into an industrial vacuum – chances are you’re more of a car owner, than a car lover. Exterior detailing involves four main activities. The first is to prep wash the exterior to remove dirt, dust, and other loose contaminants. Next, the paint is cleaned and rejuvenated as necessary to make the paint surface look great. Then, protection is applied to the paint surface to keep it looking great. Finally, other exterior surfaces are detailed. Before beginning the exterior detail, conduct a complete inspection of the outside of the vehicle. Check the bumpers, spoilers, and rocker panels for scrapes, scuffs, and excess kicked-up foreign material like tar and road striping.

    What you’ll need depends on the condition of your car’s finish. If your car has been regularly washed and waxed, you will probably only need a few detailing products:

      1. Microfiber towels (the more, the merrier!)
      2. Black-trim treatment
      3. Spray-on detailer
      4. One-step polish/wax
      5. Wax applicators or orbital polisher

    If your car hasn’t been waxed recently or has a neglected finish, you might need to call in the heavy artillery:

    1. Clay bar
    2. Mild polish or pre-wax cleaner
    3. Wax

    When you’re ready to tackle the job, here are some tips to help you get your car’s paint back to a showroom shine.

    • Prep Wash: First, conduct the prep wash. The purpose of the prep wash is to remove loose dirt, dust, and debris from the vehicle. Since the vehicle is to be detailed and wax applied, it is permissible to use harsher cleaning chemicals during the prep wash. Remember to always wash from the top down. This process also includes wheels & wheel wells. Maintaining a clean finish will help prolong your wax or sealant on your paint. This step should be done weekly.

    • Claying: Some technicians prefer to use detailer’s clay during the prep-wash step. If doing so, first wash the vehicle and rinse it thoroughly. Then clay the vehicle, using a new batch of car wash shampoo as clay lubricant. Finally, rinse the vehicle and thoroughly dry it. Using detailer’s clay during the prep wash is recommended for vehicles with minimal surface contamination. The advantage of claying as a separate step after drying the vehicle is that you can be more thorough and monitor your results as you rub the vehicle’s surface with the clay. After claying the car, the surface should feel noticeably smoother. Periodically flatten and fold the clay to expose a clean surface. There’s one major caveat: Don’t drop the clay! Dropping the clay renders it useless, as it will pick up dirt that can scratch the car.

    • Polish: Next, perform any necessary polishing steps. The purpose of polishing the paint is to remove minor sub-surface damage and shine the paint surface. A true polish will not add any protection to the paint surface – this is saved for the waxing step. Polish smooths, clarifies, and cleans the surface of your car. Polishing will remove some small scratches, but it can also remove paint, so if you polish by hand, be careful to use light pressure. This step should be done 1-2 times a year.

    • Protection: Once the vehicle’s paint has been rejuvenated to your satisfaction, it’s time to protect that fresh paint surface with either wax or paint sealant. A high-quality wax will typically provide three to six months of protection. A polymer paint sealant will typically provide six to twelve months of protection. This step is your protection for your paint, it will also add gloss and wetness to the paint. Apply the wax directly to the applicator, not the car, and work on one small area at a time. This step should be done every 2-6 months.

    • Final Detailing: Next, spend some time on the other exterior surfaces that may need attention. For example, chrome trim can be polished, the wheels and doorjambs can be spray-waxed and wiped, and the windows should be cleaned and wiped to a streak-free finish.

    The most visible and possibly most important part of any detailing job is the exterior. Exterior detailing consists of rejuvenating and protecting the exterior surfaces of the vehicle. taking into consideration the condition of the vehicle, perform the necessary steps to make the exterior look as new as possible. Properly cleaning and treating your car’s paint will add more to your car’s appearance and value than anything else you can do to it. You can always schedule an appointment with your local professional detailer.
