General Tips

Before you begin, please read this cautionary information:

  • The city does not endorse specific brands of products
  • Always use caution when using dangerous and toxic chemicals.
  • Test your removal methods and materials on a small, unimportant area to be sure they work without causing damage. 
  • Hire a trained professional for valuable surfaces, historic buildings or unstable materials. 
  • Remember: Always read product labels and follow all manufacturer instructions and recommendations. Most of the products identified above are flammable - use caution and follow safety directions when using these products. Always use proper safety clothing and equipment (including gloves, safety glasses, etc.).
The following are tips for removing graffiti from various types of surfaces:

Metal Surfaces

  • Try wiping the graffiti with a citrus based cleaner, common paint thinners (such as mineral spirits), rubbing alcohol or lacquer thinner with a soft cloth.
  • Try to remove it by rubbing with steel, bronze wool, or light sandpaper. Monitor the surface for damage.
  • Try power-washing it with a pressure washer. It is not recommended to exceed 700 psi.
  • If none of these methods work, paint over the graffiti.

Wood Surfaces

  • If the wood is painted, try using mineral spirits to remove the graffiti.
  • Try power washing with low pressure. It is not recommended to exceed 700 psi. Monitor the surface for damage.
  • Try to sand the wood and re-paint or stain.

Plastic Surfaces

  • Try wiping graffiti with a citrus based cleaner or rubbing alcohol with a soft cloth.
  • Do not use paint thinners as they can soften the plastic and can cause clouding (if clear plastic) or permanent tackiness of the surface.

Glass Surfaces

  • Try removing painted graffiti from glass by using a razor blade to carefully scrape it off with a citrus based cleaner or glass cleaner. Use the razor blade in a holder and scrape at a 30-degree angle to the glass. Monitor the surface for damage.
  • Try wiping ink graffiti with a citrus based cleaner, rubbing alcohol, or a glass cleaner with a soft cloth.

Masonry Surfaces

  • Try power-washing the graffiti with low pressure with a citrus based cleaner. It is not recommended to exceed 700 psi. Be careful in selecting the type of tip you use in the pressure wand. Too narrow of a tip (such as 0 degree) will etch the masonry surface leaving a perfect outline of the graffiti removed. Monitor the surface for damage.
