Graffiti has long been a part of social structure in urban society. Although sometimes pieces may be regarded as street art, most instances of graffiti are often simple tags that offer disputed aesthetic benefits. Therefore, most governments view graffiti as a disservice, and have banned the practice. However, since most of the graffiti cases take place in public spaces, local governments are responsible for the removal of graffiti to keep the beauty of the shire, city council or local city.

Graffiti as a negative externality
The government sees graffiti as a negative externality because it largely inhibits or diminishes the beauty of a local community. This can often stigmatize the environment or community by being labeled a low socioeconomic area. Indeed, this converts to a pressed home price and has a strong correlation with local crime and gang activity. Given the huge cost graffiti inflicted on local communities, the government takes on the burden of negative externalities, through elimination. Due to the nature of graffiti, it is virtually impossible to eliminate, despite changes to the law to increase fines for committing such violations.

Deletion method
The government takes a different approach to removing graffiti, often depending on their resources. These approaches have been developed and shifted due to greater movement in the cleaning industry, inventory costs and final outcomes of removals.
Cat out
This method involves painting over graffiti, so it can no longer be seen. It is considered a low cost method and has historically been used extensively by the government. However, over time the negative effects of this removal method begin to surface. Although effective for painted walls, these removal options often cause poor results on other surfaces, as they appear out of place and develop a "patchwork effect" on the surface. Furthermore, if this method is used regularly on the same wall or surface, the paint begins to peel, leading to the method being an ineffective long-term strategy for graffiti removal.
Chemical removal
This method completely eliminates graffiti in earnest. It is a cleaning product with an active chemical that removes graffiti from the surface. This method is very effective, however, with poor chemical applications, this approach has been found to damage the surface, especially the painted surface. In these cases, paint together with graffiti is stripped, leading to poor results. In addition, the increasing prevalence of environmental sustainability makes this method an increasingly outdated method of elimination.
Graffiti removal mechanism
There are four controllable factors that must be understood when removing graffiti.
- Time - The longer the contact time the deeper the busting graffiti will penetrate. The more sensitive the surface the shorter the time the graffiti product is on the surface.
- Temperature - The warmer weather speeds up the rate at which graffiti remover products operate.
- Agitation - When the graffiti removal product is applied by using a coarse brush or polisher, it helps in breaking the bond between graffiti and the surface. NOTE: be careful on sensitive surfaces, otherwise the underlying surface may be damaged.
- Chemicals - Use the right chemicals for the task at hand. To offset any subtraction of one of these variables to increase one of the other variables ie Should the temperature be cold, increase the contact time between graffiti and graffiti eraser, or you can raise the temperature, using the system's hot water pressure wash.
Eco-friendly deletion
This method involves the use of organic products that remove graffiti from the surface. This approach is comparable to the cost of chemical or paint removal, and often has lower benefits or no safety and health risks.
Graph on the historic surface
Many graffiti removal methods involve abrasive processes (wire brush, sand blasting, etc.) or the use of potent and potentially harmful chemical solvents that can damage historic fabrics such as historic building stone facades. Laser cleaning (using lasers from Nd: YAG wavelength), though more expensive, tends to be more appropriate for historic rocks. Some chemical cleaning agents may also be used with inert materials, in which case chemicals are usually used first to dissolve pigments, followed by a poultice to pull pigments in solution out of the substrate. The removal of graffiti from surfaces and historic objects should only be done by trained and skilled personnel.
Management
The government has found that the sooner a piece of graffiti is removed, less future graffiti takes place in that location. As a result, several different graffiti removal management methods have been developed to efficiently locate and remove graffiti.
Reactive
The government can not regulate the removal of graffiti until they realize graffiti exists. The Reactive Elimination Method depends on the government waiting for the call from the concerned citizen. There are various community programs that help raise awareness of graffiti for immediate removal. This method is effective in non-regular cases, and in environments with concerned and persistent citizens, but for locations with chronic graffiti levels are rarely reported. This is due to the futility of allegedly reporting graffiti.
Proactive
Government with more foresight and resources including checking regimens with their graffiti removal management. This inspection highlights graffiti violations faster than Reactive Removal Management. This method has been adopted in most major cities, where there is considerable economies of scale to make this kind of operation feasible.
In addition to inspection, Proactive Removal Management uses sealants to protect vulnerable locations of graffiti. Sealants protect the surface and significantly reduce the cost of removing graffiti from the surface. Initially this is only available for painted surfaces, but the product has been designed to protect various surfaces, such as brick and concrete.
Predictive
A new and emerging approach to graffiti removal management is Predictive Removal Management. This involves using a database of information about graffiti incidents within the city. These are often developed by government or graffiti removal service providers. This database then mined data to determine the pattern in the graffiti violation. This can then be used to adapt more accurate checks, as well as allowing authorities to allocate resources more efficiently. This reduces the time it takes to find and remove graffiti.
