Open / Close & Equipment Checks: the full procedure
Start the site up and shut it down the same way every day so equipment, chemicals, and the lot are ready and safe.
- Applies to: Opening/closing attendants, shift leads
- Frequency: Daily (open and close)
- Scope: Covers the open and close routine that gets the site running and safely shut down. Equipment start/stop sequences and any chemical or water checks DEFER to the manufacturer’s manual, product SDS, and the discharge permit; this SOP owns the order and accountability of the routine.
What you need
- Open/close checklist
- Equipment manufacturer start-up/shut-down guide
- Chemical level gauges
- Cash drawer/safe
- Lights and signage controls
- Maintenance log
The procedure, step by step
- Walk the site first — On open, check the lot, bays, and tunnel for hazards, debris, and overnight issues before powering anything on.
- Start equipment per the manufacturer sequence — Power up pumps, conveyor, dryers, and controllers in the manufacturer’s start-up order and confirm no fault codes.
- Check chemical and water systems — Verify chemical levels and that reclaim/water systems are operating; top up or flag per the owner’s process (handling per SDS, water per permit).
- Ready the front-of-house — Set the float in the drawer, power the POS, raise signage/lights, and confirm menu and membership terminals are live.
- Run a test vehicle or test cycle — Send a test cycle (or first car) through and confirm each wash stage fires before serving customers.
- Close: shut down in manufacturer order — At close, run the shut-down sequence, relieve/secure systems per the manual, and confirm equipment is safely off.
- Secure cash, log issues, lock up — Count and secure cash, log any equipment issues for follow-up, switch off signage/lights, and lock the site.

Frequently asked questions
What should an opening attendant check first?
Walk the lot, bays, and tunnel for hazards and overnight issues before powering anything on, then start equipment in the manufacturer’s sequence and confirm no fault codes. Check chemical and water/reclaim systems, ready the POS and float, and run a test cycle before the first customer. Equipment sequences defer to the manufacturer’s manual.
Why run a test cycle before opening?
A test cycle confirms every wash stage fires before paying customers arrive, so faults are caught on an empty pass instead of on a customer’s car. It also verifies chemicals and water systems are flowing. Any fault should be addressed per the equipment manufacturer’s manual rather than running customers through.
