Polishing your car is a great way to fade small scratches and imperfections. Find out how with our handy guide. Since 2007, Essex-based Bilt Hamber has quietly established itself as a car care tour de force, formulating home-grown – and frequently class-leading – products that are often tremendous value for money too. Auto-wheel is a case in point. Three cleaners in this group test pip the rest, and Auto-wheel is the best all-rounder of the lot. The safe, pH-neutral brew is a doddle to use: spray it on, wait until it turns red, then rinse off and dry. Its brake-dust-removing power has to be seen to be believed, and agitation simply wasn’t required on our test wheels. div>
