Wash your car often, it's easier to clean.
Wax it! The more wax you have between the clearcoat layer and the elements, the more protection you have. Protect the clearcoat and protect the paint.

- About the Air Shammee Blow Dryer
The credit card reader accepts Visa, MasterCard, American Express and Discover. It also accepts your ATM, bank card or check card with a Visa or M/C logo.
Our credit card system allows you to buy as much time as you would like to use. It places a “pre-authorization” or “pending” amount of $15 on your credit card or debit card account. You may see it on your account. Once the actual amount has cleared, the $15 pre-authorization falls off and you will see the correct charge. This may take more than a day and is a function of the banking system and is not in the control of College Park Car Wash.
When your card is approved, the STOP light will start blinking, and you can select service functions from the menu. The minimum charge is $5, for which you get bonus time equal to $1. Total start time is 9 minutes. If you need more than that, it counts up $.25 at a time, to the maximum $15 (24 minutes). It is important to press the blinking STOP button when you are finished. The display will show you the total charge. If you need a receipt, drop us an email and we will gladly furnish you with a receipt by reply email. If you feel that you have been charged incorrectly, please drop us an email, and we promise to take care of you.
The Air Shammee is just air at about 180 mph. It is great for getting water out of nooks and crannies like your mirrors and rims, and blowing off your windows. Try it, you'll like it.

If you buy $5, you get $1 in bonus time.

Our credit card system places a $15 "pre-authorization" or "pending" amount of $15 on your credit or debit card. Once the actual amount you spent at the car wash cleras, the $15 pre-authorization hold falls off and you should see the correct charge.
