Until recently, brick and stone cleaning methods lacked much in terms of specification and control. This has resulted in contractors offering a wide variety of services without due regard to the consequences of their effect. In particular, insufficient consideration was given to the relative susceptibility of natural stone materials to deteriorate as a result of the cleaning process.
The type of soiling also needs to be taken into account, soiling caused by an external agent is completely different to damaging crust-formation on the surface of materials like limestone, but this is rarely considered. Biological surface soiling is complex and can be caused by bacteria, algae, fungi or lichens. Two popular methods of cleaning brick and stone have been adopted by the industry, plus a number of specialised but less common techniques are available. The main physical methods include brushing, rubbing, washing and steaming.
The main chemical methods can be applied as liquids or poultices, using alkaline treatments, acidic treatments or organic solvents, depending on the nature of the soiling and the type of underlying brickwork or stone. The latest specialised techniques use laser technology, ultrasonic equipment, heat lances, gypsum inversion, bacteria, poultices and specially formulated gels. Not all treatments are suitable for all types of materials, and extreme care needs to be exercised when deciding which cleaning method to minimise the risk of damage.
