Got an interior detail done by Onyx Diamond Detailing and it came out amazing. The seats, carpets, and all the small details were spotless—my car looks and smells brand new inside.
Super professional, on time, and really takes pride in the work. Highly recommend if you need your interior cleaned right.

My car was absolutely disgusting before bringing it here, after picking it up it looks and smells better than when I picked it up from the dealership!! Amazing job!

I had an amazing experience with Will at Onyx Diamond Detailing! My car looks brand new inside and out — they paid attention to every little detail, from the upholstery to the rims. The shine on the exterior is incredible, and the interior smells so fresh and clean. They were professional, on time, and clearly take pride in their work. I highly recommend them to anyone looking for a top-quality car detailing service!

Frequently Asked Questions
Do I need to provide water or electricity for the mobile detailing service?
No, not at all! Our mobile detailing unit is completely self-contained. We arrive with our own commercial-grade generator for electricity and a specialized premium water tank. All we need from you are the keys to your vehicle.
What areas do you service?
We are proudly based in Denison, Iowa, and provide fully mobile services within a 35-mile radius. This includes surrounding communities such as Carroll, Harlan, Schleswig, Vail, Manilla, and Charter Oak. If you aren't sure if you fall within our service zone, just give us a call!
Do you have a physical shop location, or are you only mobile?
We offer the best of both worlds! While our mobile unit brings top-tier detailing straight to your driveway or workplace, we also have a fully equipped physical shop available. This is ideal if you prefer to drop your vehicle off, or for complex detailing jobs that require a controlled indoor environment.
