How do I use my unlimited car wash?

They place a sticker on the inside of your windshield and when you drive through the camera reads your barcode and the arm raises

Hello Patricia, thank you for your question. To use your Unlimited Wash Club Membership, simply visit your local site, drive up to the POS and your sticker on your windshield will be scanned. The gate will then open and you will be able to proceed to the wash tunnel. Thank you for being a ZIPS customer!
