Car detailing as a DIY project can be both rewarding and cost-effective.

Here's a basic guide on how to approach it:

1. Exterior Detailing

• Washing: Start with a thorough wash to remove surface dirt. Use a pH-balanced car shampoo, a high-quality wash mitt, and a two-bucket system (one for soapy water and one for rinsing).
• Clay Bar/Towel: After washing, use a clay bar or a clay towel (since you have experience with it) to remove embedded contaminants. Lubricate the surface well with a clay lubricant.
• Paint Correction: If your car has swirls, scratches, or faded paint (like your black car), you can use a dual-action (DA) polisher with compound and polish to restore shine. Start with a cutting compound, then finish with a polish.
• Waxing: After correcting the paint, apply wax (which you're already familiar with). Use either liquid, paste, or spray wax for protection and shine. Sealants and ceramic coatings offer more long-term protection if you prefer.
• Tire & Trim Care: Apply a tire dressing for that deep black look, and use a trim restorer if your plastic or rubber trims are faded.

2. Interior Detailing

• Vacuuming: Start with a thorough vacuum, paying attention to crevices and tight spots. A brush attachment helps with dusting.
• Carpet and Upholstery Cleaning: Use a carpet extractor or a dedicated fabric cleaner with a scrub brush. If you have leather seats, a leather cleaner and conditioner will keep them looking good.
• Dashboard and Plastic Trim: Use an interior detailer or a mild cleaner. Finish with a UV protectant to prevent cracking and fading from the sun.
• Glass Cleaning: Use a streak-free glass cleaner inside and out.

3. Tools You May Need

• Pressure Washer: For thorough rinsing and foaming (you mentioned you're looking for a good one).
• Foam Cannon: If you want to pre-soak the car with foam to loosen dirt.
• Polisher/Buffer: Since you're considering getting a buffer, a dual-action polisher is beginner-friendly and reduces the risk of damaging your paint.
• Air Compressor: You can use this for blowing out debris from hard-to-reach places.

Additional Tips:

• Work in a shaded area or garage to prevent products from drying too fast.
• Microfiber towels are key to preventing scratches during the drying and polishing processes.
• If you use ceramic coatings, make sure to follow the specific application instructions to get the best result.
