6. A Professional Valet
Some of us don’t mind getting a bucket of soapy water and a sponge out of the garage on a Sunday morning, but sometimes it’s better to leave it to the professionals. No, we don’t mean the guys that set up an unconvincing car wash in an empty car park. Take your car to a purpose built hand car wash, where they don’t use brushes. Let them have a go at your interior and you'll have that new car smell again in no time.
