The Benson family built Pony Express because too many car washes promised speed and delivered uneven results. We set out to get it right every time, and to treat you like a neighbor, not a number.

A membership suits commuters, families with kids or pets, and anyone who drives through East Idaho road salt, dust, snow and mud. You pay one flat price a month and wash as often as you like.

The sameclean car,every time.

Here is how we do it. Four things we get right on every wash.

  1. Equipment built for the job

    We invested in equipment made for washing cars, not in a single feature or gimmick.

  2. Products that are safe for your car

    We use Blue Coral, Rain-X, Armor All, Black Magic and Turtle Wax.

  3. The right product at the right moment

    Each one goes on at a set point in the wash.

  4. A different mix for each season

    Road salt in winter. Bugs and dust in summer. We adjust for both.
