Detailing a car's exterior involves a range of tools and products to ensure a thorough clean and protection of the vehicle.

Here’s a list of essentials you’ll need to effectively detail the exterior of a car:

Cleaning and Washing Supplies

1. Car Wash Shampoo: A pH-neutral car wash shampoo is recommended to safely clean without stripping wax or sealant from the car’s paint.
2. Pressure Washer or Hose: For a thorough rinse before and after washing.
3. Wash Mitts: Microfiber wash mitts are preferred because they are soft, which helps avoid scratching the paint.
4. Two-Bucket System with Grit Guards: One bucket for clean, soapy water and another for rinsing the mitt. Grit guards help to trap dirt at the bottom to prevent it from being reapplied to the car.
5. Wheel Brushes: Specialized brushes (soft-bristled) to clean wheels without damaging the finish.

Decontamination Supplies

1. Clay Bar or Clay Mitt: To remove bonded surface contaminants from the paint that washing won’t remove.
2. Iron Remover: Spray that chemically removes ferrous particles (like brake dust) and helps in the claying process.

Polishing Supplies

1. Dual-Action Polisher: This tool is great for beginners and professionals alike, providing a safer way to polish without risking paint damage.
2. Polishing Pads: Different levels of firmness for different stages of polishing.
3. Compound and Polish: A rubbing compound for correcting deeper scratches and a finer polish for restoring shine.

Protection Supplies

1. Wax or Sealant: Provides a protective layer over the paint, enhancing its shine and offering UV protection.
2. Ceramic Coating (optional): Offers longer-lasting protection than traditional waxes or sealants.

Other Essential Tools

1. Microfiber Towels: For drying and buffing the car without scratching the surface.
2. Detailing Brushes: Soft-bristled brushes for cleaning around badges, trim, and other tight areas.
3. Tire Dressing: To restore and protect tires’ look.
4. Glass Cleaner: For streak-free window cleaning.
5. Trim Restorer: For black plastic and rubber trim protection and restoration.

Optional but Helpful

1. Tar and Adhesive Remover: For stubborn residue like tar, sap, and adhesive.
2. Headlight Restoration Kit: If the car’s headlights are cloudy or yellowed.
3. Engine Degreaser and Protectant: For those who want to clean and protect the engine bay.

With these supplies, you can comprehensively detail a car’s exterior, not only improving its appearance but also providing protection from environmental elements.
