Those using more conventional formulas have also raised their game, and it has been interesting to see how they have matched the new generation in recent tests after a period of red domination.

One review reads “Ideal if you keep on top of your wheel cleaning and are just giving a general wash.” If your wheels require a deeper clean or have a build up of brake dust, then we’d recommend opting for one of the three options listed above instead. What’s the best alloy wheel cleaner?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.

Car wheels can take a real hammering out on the road, with dirt, salt and brake dust constantly covering them in a layer of grime. As the name suggests, the Chipex Seeing Red cleaner turns red when it’s ready to be rinsed. The manufacturer states that this pH-neutral cleaner is specifically designed to melt away the iron-dust deposit, and it really does seem to work. It really doesn’t need any scrubbing to have even baked-on dust and grime rinsing easily of the wheel’s surface and nooks. It’s not cheap, but if you don’t like to get your hands dirty, this is a great option that’s safe for any type of wheel.
