When you arrive, always park in the bay number you booked.
Once parked, turn ON the switch near the pillar. This powers the lights and the cabinet.
The pressure washer uses the side water valve. Always open it and get the water running before you switch the unit on.
The cabinet is locked. Set the 4-digit dial on the bottom of the lock to the code in your booking confirmation email.
Once everything is ready, start washing with the equipment. You can check the basic washing order further down this page, and the Equipment Guide covers how to use each item in detail.
Return each item to where you found it. Never let the air hose snap back — always guide it slowly by hand.
Before you start washing, power up the equipment in three steps.
The same steps apply at both Okazaki Kitano and Okazaki Minami.
Start by pre-rinsing the entire car from top to bottom, then clean heavily soiled areas such as the wheels and lower panels. See the Equipment Guide for the full washing, rinsing and drying process.
Please check these seven points before you leave.
If the equipment is not working, check these pages right where you are.
