KOCHCHEMIE Magic Wheel Cleaner - Powerful Rim and Rim Well Cleaner; Acid Free, Dissolves Iron Particles Using Visible Red Discoloration, Excellent Adhesion and Viscosity (500 milliliters)

Not only is this very effective at removing iron and other metal deposits, it cleans my wheels much faster and comprehensively than other wheel products I’ve used. I will stick with this product from now on - though at the price I do not use it as regularly as I’d like and use a cheaper product ‘in between’ full cleans.It is also very effective at removing rust spots from other surfaces - like porcelain tiles.

Great cleaner but I would have liked a bigger quantity

You have to give it all a good scrub afterwards. Doesn’t ‘melt’ the dirt away
