How to remove graffiti
The method of removal of graffiti much depends on the surface, its location, the extent of its coverage and the materials used in creating the graffiti.
It also depends on what you can afford. The least expensive method is a bucket of soapy water, a suitable brush and plenty of elbow grease. Shame about painted or delicate walls, they might be ruined for ever.
The rising tide of graffiti has led to a dedicated task force and specialist chemicals and treatments to deal with it. Private companies are employed to tackle the graffiti as it is reported. We, the tax payer, have to pay for it.
Employ specialist graffiti cleaners or DIY ?
When graffiti is discovered, a decision needs to be made about who is going to remove it and when.
Generally, small scale attack that involves a small amount of graffiti can be cleaned by hand. For example, someone paints a slogan on your garden fence. You know that it can be removed using an abrasive cloth and plenty of soapy water. It's a nuisance and wastes your time but it is something that you can manage yourself.
Graffiti on painted surfaces is best dealt with by painting over the graffiti.
Businesses and large organisations could allocate a caretaker or cleaner to deal with small otbreaks of graffiti, however, for large organisations such as councils, the occurrence of graffiti attack is too frequent and the work is usually outsourced to specialist graffiti removal companies who spend all their time cleaning graffiti in an area.
Anyone with a building or monument of any importance would have to employ specialists for insurance purposes. The risks are greater if treatments go wrong.
