“Initially I didn’t get on with carpro inside as it seemed streaky and no better than an apc. After racking a filthy interior with it on a carpro inside glove and a detailing brush I’m well impressed. Made plastic trims, alcantara and leather like new. The trick is to follow it with a damp microfibre to remove it. It also works brilliantly diluted 1:1 and could probably go further than that and still work well.”
