How to Use Graffiti Cleaners

Removing graffiti markings usually takes very careful effort to avoid damaging the building even further.

First, before graffiti cleaner is used, it is very important to perform a “test patch” on the building’s surface. This testing is necessary to determine the compatibility, yield, thickness and dwell time needed for the particular graffiti removal job. The material safety data sheet that comes with the graffiti cleaner should also be reviewed carefully because this sheet gives out important information on health and safety considerations during handling and application.

Carefully take note of the specific “soak in” time needed to remove the graffiti. Smooth surfaces can take only minutes to be cleaned with a simple application of the remover, agitating the surface, and a quick wipe and rinse. A porous surface like brick and concrete has a longer “soak in” time, around 15 to 60 minutes, and often requires a second application.

To complete the graffiti removal process, use a power wash (note: a power wash is a great force of water coming through a hose and washes off the building) that has the capability to provide the least amount of water pressure. The process of removal requires a good remover to soften the graffiti, and the consequent low-pressure removal by a power washer will ensure no etching or scarring to the building surface.

As alternative to power washers, graffiti removal can also be done using spray bottles, sponges, rags, nylon brushes and pads, although extreme care should be taken to avoid scarring.
