Why so many steps
A lot of people think washing a car just means using car wash soap. Actually, contamination on the paint falls into three categories:
- Loose contamination: dust, dirt, leaf debris → pre-wash, foam treatment
- Bonded contamination: iron fallout, sap, bug remains, tar → treated separately with iron remover, clay, and tar remover
- Chemical contamination: mineral deposits, oil film, wax residue → degreasing, specialty cleaners
Car wash soap alone only handles the first category. The second and third need different tools and products.
The complete 8-step process
01
Pre-wash
Before you start, touch the body panels. If the car was just driven or sat in the sun and feels hot, park it in the shade and let it cool back to ambient temperature, no more than about 40°C, before washing, so the product doesn't dry on the paint. Before your wash mitt touches the body, rinse off loose dust and grit first. Dilute DANRUO Touchless Pre-Wash with water, cover the whole car with a foam cannon, let it soften the stuck-on dirt, then rinse with a pressure washer. The most common result of skipping pre-wash is heavy swirl marks in the paint.
02
Foam contact wash
After pre-wash, dilute Foam Car Wash and cover the whole car evenly. Let the foam sit for a bit to soften the dirt, then start at the roof with a wash mitt — never circular motions, always straight lines in one direction, top to bottom. Pre-wash products are mostly alkaline, so the contact wash both wipes off the thin layer of dirt the pre-wash missed and rinses away the alkaline residue it left behind. Don't skip this step after pre-washing.
03
Wheel and tire cleaning
Dilute Wheel Cleaner per the bottle instructions and spray it over the wheel surface, avoiding hot brake discs. Let it sit 3 to 5 minutes, gently brush the gaps with a soft brush, then rinse clean with a pressure washer.
04
Iron fallout treatment
A must for any car about to get a coating or a protective layer. Spray Iron Remover over the whole car, let it sit for 3 minutes, then rinse clean with a pressure washer. No rubbing or scrubbing needed.
05
Clay treatment (optional)
Dilute Clay Lubricant (never weaker than 1:10) and spray it on both the paint and the clay. Glide the clay bar lightly to lift off iron fallout, airborne dust, overspray, and sap specks stuck in the paint. Re-spray as soon as a spot dries; never clay dry. Use a fine-grade clay on PPF or color-change wrap. Recommended about every six months.
06
Degreasing (required before coating)
Use Prep Degreaser Spray to strip off any wax or oil left from before, bringing the paint back to bare condition so the coating bonds properly. Follow the bottle for dwell time and wiping method — message us on WhatsApp first if you're not sure.
07
Polish or maintenance product (as needed)
If the paint is in good shape, go straight to Angel Coating Guard (1:1000 dilution in a hand pump sprayer — 1cc concentrate to 1000ml pure water; a PA foam lance uses a different ratio, check the bottle). If there are swirl marks, polish first, then apply the maintenance product. For deep scratches, run the full 3-piece compound set.
08
Detail finishing
Apply Tire & Trim Oil to the tire sidewalls, Glass Coating Spray on the glass, All-Purpose Cleaner on the interior, and clean leather seats with Leather Cleaner, then follow up with a leather conditioner.
Shortened routines for different situations
Scenario A: weekly routine wash (30 min)
Step 1 (pre-wash) → Step 2 (foam) → Step 3 (wheels) → Step 8 (quick finishing)
Scenario B: monthly deep care (2 hours)
Step 1 → 2 → 3 → 4 (iron fallout: recommended every 3 to 6 months, skip in months it's not due) → 7 (Angel Coating Guard maintenance — remove oil film and degrease first) → 8
Scenario C: quarterly full care (4 to 6 hours)
Step 1 → 2 → 3 → 4 → 5 (clay) → 6 (degrease) → 7 (No.10 1000 grit polish) → 7.5 (Angel Coating Guard: after polishing, wash and degrease the car first, then apply while the body is still wet) → 8
Scenario D: full pre-delivery process (a full day)
Run all 8 steps. For polishing, judge the paint condition first to decide where to start. For deep scratches, heavy oxidation, old-car restoration or accident-damaged cars, start with the 80 grit heavy cut and run the full 3-piece set (80 → 600 → 1000). If the paint damage is within 1000 grit range, you can go straight to a one-step polish with the No.5 600 grit and a dedicated wool pad.
Wrap-up
Washing a car can be quick or it can go deep. What matters is knowing what each step is for, then choosing how far to go based on your time and needs. Get the process right, and the car pays you back by looking clean.
