Applied to a motorcycle aluminum rim, which hadn't been thoroughly cleaned in over 5 years. It eliminated tough dirt that wouldn't come off even when the motorcycle was washed at the gas station. A simple spray, without using a sponge, was enough to remove 90% of the dirt. I recommend this product, especially at the price of €5, you won't find anything comparable.

I had not cleaned the rims internally for 14 years. Only what came out with the car wash. With one pass, it removed almost all the blackness using a brush for rims. It has a pleasant soft scent and easy application. For its price, it is superb. The only negative is that it required more than 25% of the content.
