SM.AutoDetailing

I started SM.AutoDetailing at 13 because I wanted to take things into my own hands and do something most people my age weren't even thinking about. With a basic kit and my own money, I got to work — no investors, no handouts, just me figuring it out one detail at a time.

Three years later, this is still a self-funded, owner-operated business. Every car I touch gets the same standard: full attention, no shortcuts. That's what I built this on and that's what it's staying on.

What drives me isn't just cars — it's the standard. The goal has always been to offer a level of quality that speaks for itself, and to earn every client's trust by delivering that every single time.

Our philosophy
Every package. Every time.
No exceptions.

We don't believe in a "good enough" service depending on what you paid. Every package we offer has been built and refined with one outcome in mind — you walk away impressed. That's not a guarantee we throw around. It's the standard we hold ourselves to on every single job.

"The thing that has never changed is our attention to detail and desire to push ourselves to offer the highest quality service."

— Demian, Founder of SM.AutoDetailing

Rethinking social media: a resource for teen entrepreneurship

Journalist Giselle Espinoza found SM.AutoDetailing on Nextdoor, booked a detail, and then decided the story behind the business was worth telling. The piece explores how Demian — founder of SM.AutoDetailing — started his business at 13, self-funded it from the ground up, and turned the same social media most teens scroll past into a genuine learning tool and business launchpad.

"Do not give up. It just gets hard for a long period of time and people think it's over... I have been through that time, I just tell myself I know it is going to get better."

— Demian, featured in the Daily Journal

"That's the most important thing to me actually, that it's mine."

— Demian, on self-employment
