Onyx Auto Spa — Scottsdale & Phoenix
Recurring, safe maintenance washes designed for coated and uncoated luxury vehicles — at your home, on your schedule.
From $125
If you've invested in a ceramic coating or just want your daily driver to always look its best, recurring maintenance washes are the answer. Onyx Auto Spa runs weekly, bi-weekly, and monthly maintenance plans across Scottsdale, Phoenix, Paradise Valley, and beyond.
Every maintenance wash uses pH-neutral shampoo, touch-free foam pre-soak, two-bucket method, and a deionized-water final rinse — the right chemistry to preserve your coating and your finish.
Why It Matters
pH-neutral, coating-safe soaps that won't strip ceramic protection.
Same lead technician on every visit — no rotating crews.
Bi-weekly and monthly clients pay less per wash than one-off bookings.
Members get priority scheduling around weekends and events.
Every appointment follows the same careful, documented process — no shortcuts.
Touch-free chemistry lifts road grit before any contact.
Coating-safe shampoo with microfiber mitts and grit guards.
Cleaned and dressed every visit — not just on full details.
Spot-free rinse and microfiber dry to preserve gloss.
Optional ceramic booster spray to refresh hydrophobics between full services.
It's a planned, recurring service designed to preserve protection and finish — not a one-time scrub. We use coating-safe chemistry and the same technician every visit.
No. We only use pH-neutral, coating-safe shampoos. Many maintenance washes include a ceramic booster spray to refresh hydrophobic properties.
Yes — fleet and multi-car maintenance is one of our most-requested services in Paradise Valley, Silverleaf, and DC Ranch.
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.
