Paint, crayon and marker vary widely in chemical composition. Generally speaking, blue and green colors can be more difficult to remove than red or black. The thicker and older the marks, the harder/longer you need to work to remove them. Agitation with a non-abrasive nylon brush or polyester scrub pad will speed removal. Since GRAFFITI GONE! Is water based, if a 2nd application is needed, it can be done immediately. If you're not sure the product has soaked enough, agitate it gently to see if the graffiti is loose enough to be rinsed. If not, let it soak longer before rinsing.
