Was wondering if anyone else had the problem of products staining a asphalt driveway. I can tell where the vehicle sits from washing,,and not sure if it is the shampoo or the all-purpose cleaner I use for wheels and wheelwells,,but it really fades the black pavement and makes it look kinda crappy . It fades where ever the pavement gets wet ,,so I think it must be the shampoo,,which is liquid glass wash. Maybe need to switch wash soap ?? Thanks
