Shell Car Wash is the wash service run at Shell petrol stations around Singapore, offering a hand wash with add-ons like waxing while you refuel.
It runs at more than 20 Shell stations across the island, from Alexandra and Boon Lay to Tampines, Punggol and Yishun. Hours vary by station: a few (such as Guillemard, Marsiling and Paya Lebar PIE) run 24 hours, while most open roughly 9am to 9pm daily. Pricing is per wash package at the station.
Worth it for: a quick wash bundled with a petrol stop, rather than a booked detailing session.
Where and hours: check the station list and opening hours on Shell's car wash page. There's no central booking; you go to the station.
