Fall out is a PH neutral bleeding wheel cleaner, so called due to the nature of the product changing colour when it is activated on wheel/body of the vehicle.
Directions of use:
Spray on and let the product change colour as it dissolves all the contaminants effectively bleeding as it turns purple.
Simply wash off with a power washer.
Although designed as a non-contact wheel cleaner, more stubborn dirt may require a little agitation.
