The most important step to take in order to keep graffiti vandalism off of your property is to be vigilant and remove graffiti as soon as possible. The faster graffiti is removed the less likely it will reoccur. The longer graffiti stays on your property the harder it becomes to remove and the more additional graffiti it attracts. You may also commission an artist to create a mural or graffiti art on your property and apply for an exemption.

Removing Graffiti on Specific Surface Types
It is often difficult and frustrating to remove graffiti from your property. In general, removing graffiti involves the use of a cleaning agent and some patience.
- Determine the porosity of the surface (masonry surfaces being the most porous, painted metal/vinyl surfaces the least).For very porous surfaces the cleaning agent should be allowed to sink in to the surface and be agitated (with steel wool/wire brush) while sinking in.
- For less porous surfaces the cleaning agent may not be allowed to soak in and should therefore be removed with a cloth, so as not to damage the existing finish.
Metal and masonry surfaces:
- Power-wash with a pressure washer
- Paint over the graffiti
- If the wood is not weathered and is sealed with paint, stain or sealer, remove it by wiping it with mineral spirits
- Power wash it with a pressure washer
- Try wiping graffiti with a light, penetrating oil. Do not use paint thinners as they can soften the plastic and can cause clouding (if clear plastic) or permanent tackiness of the surface.
- If this does not remove the graffiti, paint over it.
- Scrape it off. Use a razor blade in a holder and scrape at a 30 degree angle to the glass.
- If the paint does not come off completely after using the razor blade, use ultra-fine bronze wool with water to gently rub the remaining paint off.
In addition, there are several different products available that can be used on their own or with a power washer. Be sure to research the product to ensure that it is suitable for the intended application. When painting over graffiti, be sure to obtain the right type of paint for the location and type of surface you are painting. Make sure that the method chosen is done safely and that it will not cause damage to the structure, to the environment or to you.
