A guy standing next to his pickup in one of our Lawrenceville bays asked me a question the other day that I hear all the time:
"Be honest with me—is washing my truck in a self-serve bay actually better for the paint than running it through an automatic?"
With harvest dust still in the air and road salt just a few weeks away here in Southern Illinois, it's a fair question. An automatic wash is quick, and there's nothing wrong with using one when you're in a hurry.
But here's what I told him: a machine only knows one routine.
If it's a touchless automatic, it has to lean on harsher detergents and fixed spray angles to make up for not touching the vehicle—which often leaves a thin road film behind on lower rocker panels, wheel wells, and the back glass. And if it's a soft-touch brush tunnel, those spinning rollers can't see whether the truck right ahead of you just drove out of a muddy field road. Any grit left in those brushes gets spun right across the next hood in line.
When you pull into a self-serve bay, you're the one holding the wand:
1️⃣ You blast the grit off first. Rubbing dirt across dry paint is the #1 cause of swirl marks. Hit Tire Cleaner on the wheels and lower rockers, lay down Pre-Soak or Wash Soap, and use high pressure to knock all the loose grit off before anything ever touches your clear coat.
2️⃣ The 3-second Foamy Brush habit. Before you put the Foamy Brush on your vehicle, aim your high-pressure wand right at the brush head for 3 seconds to blast out any leftover grit from the last wash. Clean bristles + thick suds = a safe scrub on stubborn road film.
3️⃣ You spend time where salt and mud actually hide. Wheel wells, rocker panels, trailer hitches, and bumper seams get as much attention as they need.
4️⃣ Finish with Clear Coat + touch-free air drying. Lay down a pass of Clear Coat while the weather is still mild, then use our Super Air Shammee II hand-held air dryers (in Lawrenceville Bays 1–4; coming soon to St. Francisville!) to chase the water out of mirrors and seams without dragging a gritty towel across your paint.
No quarters in the cupholder? Bays 2–5 in Lawrenceville have Tap to Pay on a count-up timer, so you aren't racing a buzzer while you get the lower panels right. (Heading to St. Francisville? Bring quarters—$2.00 starts the bay!)
I wrote up the full breakdown—plus our step-by-step paint-safe bay routine—on our website blog today (link on our Page profile and in the comments below!).
Both washes are open 24/7 whenever you're ready:

See you in the bays! 🫧
