About J’s Ultimate Hand Car Wash

boise car wash ownerHello, I’m Jason Smullin, owner of J’s Ultimate Hand Car Wash. Friends and family call me J for short. When you visit, there’s a good chance you’ll see me. I’m usually here before we open and I stay until closing, six days a week. If you ever have a question or concern, feel free to find me. That’s one of the things people notice different about J’s – there’s not some corporate office to go through when you want to speak with the boss.


There are other things different about J’s. We help people who have been turned away at other washes – people with work trucks, specialty cars, sports cars, antique cars, large trailers, motorcycles, boats and RVs. We like to say, “If you can bring it in, we can wash it” and we really mean it. And we wash standard cars, too. We make detailing and hand-washing affordable and our prices are as competitive as anyone’s.

I’ve been in the car wash industry since 1991 and I’ve owned J’s since 2004. There’s nothing I like better at work than seeing someone drive off the lot with a smile, feeling good about how their car looks.  I’m a Blackfoot native, but I’m raising my family in Boise. J’s has a strong commitment to the community and we often donate washes for local clubs and groups.
