SHADOW AWAY GRAFFITI REMOVER This graffiti remover is made to work after other products have failed or when you have large tags on concrete or porous surfaces. Shadow Away turns into a gel after it is sprayed on to penetrate porous surfaces and cling for vertical application. This is designed to remove shadows of paint or marker that have been left from previous failed attempts of removing the tag. This needs to be applied to a dry surface and multiple applications should be sprayed until the entire thickness of the paint has been affected to be able to wipe it off with a cloth or washed off with a pressure washer. Shadow Away is also pH neutral, biodegradable, non corrosive and contains no petroleum distillates.
