Halfords Bug & Tar Remover
There wasn’t much between this Halfords cleaner and the similar Meguiar’s version. Both have a polish-like smell and are white, so you need to make sure all the formula is removed from grilles and mesh. A pain, but you do get effective cleaning – albeit a step behind the Gold Class Meguiar’s. This Halfords version also needs to be removed with a damp cloth, but it’s almost half the price.
