For the last however many years I’ve just always popped my car through the car wash. However I’ve now bought a soft top convertible so I can’t. Just been looking at Halfords website and there are so many different car shampoos, waxes, wheel wash, tyre wash etc. What do i actually need? Which ones are essential? Which are for professionals/ obsessive? I’m guessing we’ve moved on from the 1980s, fill a bucket with soapy water and get on with it.
