Onyx Auto Spa — Scottsdale & Phoenix
A proper exterior detail goes far beyond a wash. Foam pre-soak, clay-bar decontamination, sealant, and wheel/tire restoration — all at your location.
From $195
Most car washes do more harm than good. Brushes mar paint, recycled water leaves spots, and the wax sprays don't actually protect anything. A real exterior detail starts with proper chemistry, two-bucket wash, and decontamination — and finishes with a sealant or wax that actually lasts.
Onyx Auto Spa's exterior detail is the right monthly or quarterly service for any vehicle that doesn't have a fresh ceramic coating — and a great maintenance program for any that does.
Why It Matters
Loosens and lifts dirt before any contact, dramatically reducing wash marring.
Dedicated wash and rinse buckets with grit guards — never reusing dirty water on your paint.
Removes embedded contaminants — overspray, rail dust, fallout — that washing alone won't lift.
Iron-decontaminated wheels, dressed tires, and cleaned wheel wells. Often skipped — never by us.
Long-lasting hydrophobic protection that beads water for weeks, not a single rain.
Every appointment follows the same careful, documented process — no shortcuts.
Touch-free foam cannon to lift surface dirt and grit.
Dedicated wash mitts, microfiber, and grit guards.
Iron remover and clay bar to pull embedded contaminants out of clear coat.
Full wheel face and barrel cleaning, tire dressing, and exterior trim restoration.
Hydrophobic sealant or spray wax, then a microfiber/deionized water final dry.
No. A car wash is a 10-minute rinse. An exterior detail includes decontamination, wheel/tire restoration, sealant, and care for trim and glass — and takes 1–2 hours.
Monthly for uncoated daily drivers, quarterly for coated or garaged vehicles. We offer recurring plans at a discount.
Yes — fully self-contained mobile rig with filtered water and power. No hose or outlet needed.
Onyx Auto Spa comes to your home or office anywhere across the Phoenix metro. Fully self-contained mobile service, every time.
Pair services for the best results — most clients combine paint correction with ceramic coating.
