Mahalo for joining the Emerald Wash Club! Your next step is to come and see us. When you arrive, please inform a Car Wash concierge that you joined the Wash Club on the Flagship Express Car Wash website. Please have your credit or debit card ready as we will need that in order to finalize your membership. Once we have all the necessary info, we will install the small barcode sticker to your windshield so you can drive right through on your next visit. Mahalo!
