This wheel cleaner is made from premium biodegradable ingredients and is safe for all types of wheels. More importantly, it's safe for you and the environment. Any wheel cleaner that boasts spray-on, spray-off with no rubbing is a danger to you and our planet. Unique penetrating formula requires far less effort when cleaning wheels. The high concentrate allows the cleaner to hang on the wheel longer to clean stubborn brake dust, road oils and other deposits. A superior product with no expense spared toward the ingredients.
