Graffiti Removal


The US spends billions of dollars each year cleaning up graffiti, but a project that's in the works could make it cheaper and greener to remove.

Graffiti is a problem for cities across the country, often a sign of gangs.

While removing it can help save lives, it can be dangerous as well.

Toxic chemicals can leak into the environment.

Scientists are testing new, cleaner techniques for removing the graffiti.

They include blasting it away with crushed recycled glass or dry ice pellets and wiping it away with a mixture of soy and rubbing alcohol.

These techniques could reduce the $12 billion year spent on graffiti removal.

Once the research and testing is finished next year, the EPA hopes some of the products will be commercially produced and rolled out nationwide.
