The Future of Car Washing Is Friction-Free In the past, car washes relied on spinning brushes and cloths to scrub away dirt.Today, touchless car washes use something far more precise — chemistry. At Rice Street Car Wash in St. Paul, Minnesota, we’ve replaced friction with finely tuned formulas that break down grime at the molecular level, protecting your car’s finish while delivering a deep, consistent clean.

At Rice Street Car Wash in St. Paul, Minnesota, we know that not all dirt is created equal.Some grime comes from oil and grease; other buildup comes from minerals, salt, or oxidation. That’s why professional car washes don’t rely on just one kind of cleaner — they use both high-pH and low-pH products to attack dirt from every angle.

When you pull into a touchless wash, you see foam, water, and shine.But hidden inside that foam are microscopic workers called surfactants—the chemical backbone of every cleaning product at Rice Street Car Wash. These tiny molecules are the reason dirt loosens, oil dissolves, and water sheets away from your car’s surface. Without them, even the highest-pressure rinse would leave grime behind.
