How often may I wash my car with a monthly membership?

Just as the name states, it’s UNLIMITED! Please keep in mind during periods of inclement weather, we may not be open. Any other time, come see us as often as you like!

What is required to use one of your free vacuums?

You may use one of our complimentary vacuums after purchasing one of our Exterior or Outside Only Washes. In addition to our vacuums, we also provide complimentary towels and glass cleaner for your convenience. Please place used towels in the marked bins after use as we rewash them. We ask that you please limit your vacuuming time to 10 minutes to allow other customers an opportunity to the vacuums.Thank you in advance!

Will buffing remove all scratches from my car?

We cannot guarantee all scratches can be removed, since vehicles are treated on a case-by-case basis; for example, a deep scratch (or one that you can fit your fingernail into) typically will need to be repaired at a body shop. We can remove most minor scratches, oxidation and swirl marks depending on the level of service you purchase. We recommend that you visit us and allow us to review your vehicle’s condition together with you present.

How long should I expect to wait if I purchase a Full Service Wash?

If you have a Full Service unlimited membership you should allow 10-15 minutes from the time you pull up to our gate until your back in your clean car on your way. Non-members should allow 15-20 minutes. One of the benefits of having an unlimited membership plan is that your car always kept clean due to frequenting our car wash as often as you like!
