Chris Keen, owner of graffiti removal business KleenKeen, is contracted by Albury Council to wash off graffiti from walls and signs around the city.

But Mr Keen’s work is becoming harder as vandals come up with new ways to make the graffiti more difficult to remove.

He said taggers were adding glue to paint or using textas to smear on shoe polish.

“We are constantly updating our products because they don’t work all the time,” he said.

“It may be that one of the products will remove it a little bit but not totally, so we have to go back and look at what direction we will go in.”

Mr Keen said it was important to clean up the graffiti within 24 hours or his job was made harder.

“If they add glue to their paint then the longer it is left, the longer it has to set and become hard,” he said.

Mr Keen has been employed by the council since November 2007 to help other council workers clean up the city.

However, he said he had not received many call-outs in the past month.

“The council are taking a fair bit of it off themselves,” he said.

“Realistically, I don’t think there is as much graffiti around as there was last year, but there is still a fair bit of it going on.”

Trouble spots on the Border include bridges, road signs and the Hume Freeway’s sound barriers.

Even the Albury post office, one of Albury’s most significant buildings, was hit by vandals a fortnight ago.

The tags spray-painted across five of the building’s pillars have since been painted over.

Mr Keen said he believed the freeway barriers were hit the most.

“They are a large, clear surface for graffiti artists and police can’t be every where,” he said.

“I take the work (tags) off there so often and it is such an easy target.”

Mr Keen said large walls, like the freeway barriers, could take several days to clean properly.
