How to clean Graffiti

Whatever way one may look at it, even from an aesthetic angle, graffiti done without permission is vandalism. Therefore before taking up any graffiti cleaning project one should call the local police department and keep the photos as record. It might help to collect damages if the “tagger” is ever traced.

Removing graffiti is an intricate process and is different for outdoor and indoor scenarios.

  • Outdoor – There is a special tool that facilitates graffiti removal from concrete surfaces. It’s a pressure nozzle that blasts water and sand on the scribbling. Round silica sand is best for this kind of operation but care has to be taken to ensure that the sand is dry at all times by keeping it covered. The sand blast attachment probe has to be put in the sand and the other end has to be attached to the power washer nozzle. This method can clean paint, rust and baked grease from metal, wood and other types of masonry.

Another method is to dampen the graffiti surface with low pressure jet, apply water based paint stripper over the graffiti with a brush and let it set for 10 minutes. The paint stripper has to be rubbed into the graffiti with a scrub brush and washed off with low pressure water.
