What makes our tunnel wash the best option for your car?

Spot Free Rinse

All of our three express exterior wash packages feature our signature Spot Free Rinse that is specifically designed to leave a spot-free shine without the need of hand drying. This allows every customer to maximize their time and experience no matter what package you choose and drive away with a perfect shine.

Variable Speed Tunnel

Using DuroTrac’s conveyor belt system, we provide easy vehicle loading and unloading along with a smooth and continuous flow. By using a belt conveyor versus a traditional chain drive with rail guides, we can wash low profile wheels without having the wheels bumping through the rail guides, giving you peace of mind.

SpinRite® Technology

Experience a noticeably better clean and shine thanks to the SpinRite® car washing technology. Using their signature ShineMitt Media, it provides up to 9X the cleaning and shining of traditional foam media and the wheels run at ⅓ the speed of standard wash wheels giving you a quiet and more complete wash.

Water Reclamation System

The biggest problem with standard car washes is they use roughly 38 gallons of water each time a car is washed. Instead of wasting water, we use a 1,200-gallon water recycler with PurWater 5 Micron Filtration System to help conserve water and protect the quality of nearby water bodies.

Free Vacuums

Complete your Splash In experience by enjoying free vacuums with your wash. Open 7-days a week from 7 am to 7 pm. Available for Free in 5-minute intervals after your wash.

12 Convenient Vacuum Stalls

Our 12 vacuum stalls feature two of AutoVac’s most powerful 30 HP vacuums for a combined 60 HP of suction. Each stall is equipped with a trash can.

12X the Power

Our 12 vacuum stalls feature 12X the power than your average 5 HP wet/dry vacuums found at standard car washes and most gas stations.

AutoVac Vacuum System

Using AutoVac’s signature 600 Series Vacuum Producer gives drivers a reliable and powerful vacuum (very little maintenance required).


Each 30 HP vacuum system uses variable frequency drives to throttle up during use and down when on standby to help preserve energy.

Frequently Asked Questions

Is washing my car at a commercial car wash really better for the environment?

Yes. In commercial car washes, chemicals are filtered and sent to a water treatment center for cleaning. Washing your car the old fashion way often results in untreated waste water (including soap, oil and sludge) going into the ground and storm sewers that lead into our rivers, lakes and streams. And a driveway wash uses up to three times more water than washing at a commercial car wash!

What hours will the tunnel car wash be open?

The tunnel car wash will be open from 7 am to 7 pm.
