Get a car wash voucher worth up to £9 at your local BP station for just 50p. Simply sign up at the BP site, enter your postcode to find your nearest participating BP station and download your voucher. You can choose three levels of car wash – express, super or premium. The Premium normally costs £9, so you’re quids-in if your local station provides this! Alas, only 60 BP stations provide the premium car wash in this offer.
Once you find the deal you want, you can either print it, or just show it to the counter staff on your smartphone. If the car wash is busy, the car wash token lasts for 7 days.
