Apparently graffitiing tram and bus stops with acid is the new trend

This grey/white shadow-like graffiti is a type of etching that comes in the form of paint and spray cans and is highly acidic. The acid burns through shelter glass and leaves an unpleasant stain on the glass that is matte to touch.

Unfortunately, there has been much of this particular type of graffiti springing up across the network.

Due to the burns caused by the acid in the spray paint and the staining that occurs when trying to remove it, our teams are unable to remove this type of graffiti.

The only solution is to replace the glass of the shelter and due to budget constraints and the number of shelters affected, Yarra Trams is unable to do this.

I've received similar responses from various councils about graffiti as bus stops too. Apparently for bus stops, responsibility for removing graffiti falls on councils, but if it requires replacing the glass it's PTVs responsibility, or at least that's what the City of Melbourne tells me

Anyways, I guess if you want your racist graffiti to not be removed just paint it with acid, or, I guess, burn it with acid.
