Writing from New Orleans, La. Been doing a few hurricane clean up jobs. Search and rescue teams painted signs and symbols on many houses to designate if there were any bodies in the homes following the flooding. What is a good local product to remove this spray paint from brick? Also, there is a water line present on most houses due to nasty water sitting for a good period of time. What is good for removing this residue- white line on red brick; brown lines also. We have been using 12.5% chlorine. Any chemical tips?
