Graffiti is a widespread issue in many cities throughout the world, and Melbourne is no different. Each year, the Melbourne City Council must spend a substantial sum of money to remove graffiti from public areas. The council spends about $4 million a year on graffiti cleanup, according to the most recent data. Both the direct costs of removing the graffiti and the secondary costs of fixing the harm it caused are included in this price.
Pressure washing is one of the most often employed techniques for eradicating graffiti. Using a high-pressure water jet to blast the paint from the surface is known as pressure washing. The type of surface and the paint being used determine the amount of pressure needed to remove graffiti. 2000–3000 psi of pressure is typically enough to erase graffiti off concrete surfaces without causing any surface damage. However, a lesser pressure could be necessary for delicate surfaces, like as old structures or monuments.
Vinegar is another technique for erasing graffiti. An acidic solution like vinegar can degrade paint and make it simpler to remove. But it’s important to remember that vinegar can also harm the surface, particularly if it’s porous, like concrete. As a result, vinegar should only be used sparingly and on materials that can survive its acidic qualities.
It is crucial to employ the proper procedure when erasing graffiti to prevent harming the original paint or surface. Using a solvent-based cleaning is one of the finest ways to get rid of graffiti without affecting the original paint. Cleaners with solvent bases are made to remove paint while protecting the surface. They function by causing the paint to dissolve, making it simpler to scrub or wipe off. In conclusion, graffiti is a major issue for the Melbourne City Council and its removal costs millions of dollars each year. Graffiti removal can be accomplished with solvent-based solvents and pressure washing, but care must be taken to protect the original paint and surface. Graffiti can also be removed using vinegar, although care should be used, especially when using it on porous surfaces like concrete.
