The City does not endorse any commercial products, but the names of some products are mentioned herein to help citizens identify the kinds of products that may be useful. Graffiti is always easier to remove as soon as possible after occurrence and before the paint has fully cured.
These include concrete, wood, metal or other surfaces that has a topcoat to protect it. These surfaces are usually easier to clean because the graffiti cannot penetrate as far into the surface.
These include unpainted brick and concrete. The harder and smoother the surface, the better the chances of removing graffiti without damage or visible change. Here are some removal methods that can be effective:
If the citrus based cleaner doesn't work, apply a graffiti removing solvent, oven cleaner or paint stripper as directed
by the product's manufacturer. Wait as directed by the product's manufacturer, usually at least
3 - 5 minutes. Scrub the affected area with a stiff brush or wire brush, being careful not to damage the surface. Rinse off with a hose or pressure washer. Some of these products may be hazardous to your health, so be sure to follow the manufacturer's instructions. Wear protective goggles and gloves. Collect runoff water for proper disposal. Do not allow hazardous chemicals to enter into the storm drain system. These surfaces are usually easier to clean because the graffiti cannot penetrate as far into the surface.
As a last resort, you can paint over the graffiti. However, it is still a good idea to try to remove as much of the graffiti as possible before painting to reduce "bleed through".
