The graffiti removal on natural stone of various types can be done with the cleaning machine Tornado ACS which works reliably and environmentally friendly. There are very hard stones, such as granite on which you can use all the granules and there are very soft stones, such as sandstone or marble, on which you must work only with fine granules. In order to protect the surface from damage, the right granulate has to be used.
The cleaning equipment Tornado ACS is the ideal alternative to a high-pressure cleaner and dry ice blasting for graffiti on natural stone. You reach an area coverage of 2-4 sqm / h. On bright natural stone jet glass SG 15 is used and on dark natural stones AS 180.
The use of chemicals is generally not recommended on natural stone. Chemical cleaners dissolve the paint so that it can penetrate deeper into the pores. What remains are shadows that are difficult to remove.
