This biodegradable and water-based formula breaks the molecular bond between spray paint and the surface, making it highly effective. The versatile formula removes aerosol, enamel, acrylic, high- and semi-high-gloss paints—and can do it on a number of surfaces such as signs, Plexiglas®, street signs, vinyl and plastic, even porous surfaces such as brick and concrete. Currently it is the one and only Green Cross Certified paint remover. With the trigger spray bottle, you can perform a quick and easy application.
