The CCB credit cards that offer car wash services are the "Dragon Car Card Series (i.e. those with the word ATUO on the card)". What you can enjoy is: a car wash service at a discounted price once a week, and the car wash outlets are free of charge within 15 yuan. For car washes, if the amount exceeds 15 yuan, you can pay the excess amount. You can use points to deduct the excess amount or pay with cash by credit card.
