Bilt-Hamber auto-wash
Alongside the big Halfords and Simoniz packs, this 300ml bottle of Bilt-Hamber looks expensive
Price: £9.14 | Size: 300ml
Alongside the big Halfords and Simoniz packs, this 300ml bottle of Bilt-Hamber looks expensive. But you need just 5ml of the “highly concentrated” formula per bucket, which means it costs just 15p per wash. And despite the small amount, it foams up impressively and leaves a highly water-repellent finish, so you only have a few spots of water to dry off.
