Cleaning up "fire tagging"

[ERADiblaster]

Has anyone encountered this yet, and have you had any luck cleaning it up? I've just heard about it recently, via the Nograf Network, but there will be a lot of results if you search the Web for it. Here's one: Fire Tagging Makes Graffiti a Bit More Dangerous
It seems that some "taggers" will spray-paint their graffiti on a wall or other available surface, and then ignite the wet paint. Some are using lighter fluid. It supposedly makes the tag "permanent," but I'm hoping something like soda blasting or anything else used by power washing professionals will remove it. (Preferably anything that has already been proven to work. I haven't yet found anyone willing to lend me a concrete wall to experiment on. )

Try it out on a loose cinder block that way you don't need a donor wall. Dry ice blasting will easily remove the smoke or burn damage to brick / block walls.

Good idea, Eric. Thanks.

I don't suppose the paint/lighter fluid burns long enough or hot enough to cause spalling of any concrete it was sprayed on, or could it?
