D1801 is also highly effective at removing road grime, grease and dirt from wheels and brakes, and is ready to use right out of the bottle. The rapid colour-changing properties help to indicate that it's working to remove iron from wheels and paint. Despite being a highly effective pro-strength formula, it's still pH balanced making it safe on all wheels and painted brake components.
