Frequently Asked Questions

General Questions

Do you clean the inside of my car?

No, upon exit of the wash tunnel, we provide access to complimentary vacuums, microfiber towels, glass cleaner, sanitizing spray, and a carpet floor mat cleaner.

Do I remain in my vehicle the whole time?

Yes, you will stay in your car during the wash tunnel experience. Upon exit of the tunnel, we encourage you to utilize the complimentary vacuums so that your car is shining on the inside and the outside.

Why is washing my car at the car wash better for the environment?

Washing your car at home can use up to 150 gallons of water. When this untreated water flows into your yard and into sewer systems, it can adversely impact local waterways such as creeks, rivers, and coastal areas.

At ModWash, we use less than 30 gallons of water per vehicle, and the chemicals we use during the wash process are biodegradable and pH balanced. We reclaim and filter the majority of our water, approximately 20 gallons per vehicle, and reuse it. We have a central collection system for water that is not reused and dirt that is accumulated during the wash. After it’s collected, we redirect it to facilities that can properly handle the non-hazardous waste. These facilities are able to further refine and process it to be used for potting soil and fertilizer.

What type of vehicles cannot go thru the car wash tunnel?

  • Duelies – too large for Track
  • Vehicles over 7’6” Height x 7’6” wide
  • Vehicles with Tires over 13 1/2 “ inches will not fit on the conveyor
  • Vehicles with Excess Mud
  • Vehicles with Trailer Hitch and Roof Racks
  • Vehicles with Modifications after Market

What are the accepted methods of payment?

We accept most major credit cards and cash.

What is ModShine 3-step Fusion?
