Why choose us
More than a wash.
A craft.
Onyx Auto Refinement is built on a single belief: every vehicle in Sioux Falls, South Dakota deserves the kind of care usually reserved for showroom floors.
Safe Wash Methods
Two-bucket wash, plush microfiber, and pH-balanced soaps — never harsh brushes or shortcuts that risk swirl marks on your paint.
Premium Quality Products
We invest in professional-grade chemicals, ceramic-infused waxes, and tools built for high-end finishes — because your vehicle deserves nothing less.
High Attention to Detail
From door jambs to seat stitching, we obsess over the spots most detailers skip. Every inch is treated like the spotlight is on it.
Satisfaction Guarantee
If you spot something we missed, we make it right — no questions asked. Your happiness is the only finish that matters.
Passion-Driven Business
Onyx isn't a side hustle — it's a craft. We pour real love into every vehicle that rolls through Sioux Falls, South Dakota.
The Onyx Standard
When you book Onyx, you're not getting a rushed wash — you're getting a meticulous restoration. We combine safe wash methods that protect your paint, premium-grade products that outlast cheap alternatives, and obsessive attention to detail across every panel, seam, and surface.
