Graffiti Removal in the Streets of Gothenburg with DYNAJET

Graffiti removal in public spaces demands a method that is fast, reliable and suitable for different surfaces. In Gothenburg, DYNAJET was part of a practical training course where professionals tested how high pressure can support the removal of stubborn graffiti after chemical pretreatment. The results show what is possible when the right equipment and method are combined on real surfaces under real conditions.

The training was jointly organised by HTC, DYNAJET's Swedish sales partner, and MPE International AB, a Swedish supplier of graffiti-removal chemicals. Fifteen participants from across Sweden used the final day of the course for hands-on work in the city. This kind of application is relevant for contractors, municipal teams and service providers who need a dependable solution for graffiti cleaning under real conditions, not just in theory.

For the demonstration, a DYNAJET 350th HELI with a 300-l water tank was used. The unit could operate at four different locations without refilling, which made the work process practical and uninterrupted. That is a clear advantage when access to water is limited or when several spots need to be treated in one sequence. The demonstration also showed how professional high-pressure cleaning can help remove graffiti quickly and reliably from surfaces that have been prepared with suitable chemicals.

For operators planning similar tasks, the key takeaway is simple: successful graffiti cleaning depends on the right coordination between chemical pretreatment, mobile equipment and controlled high pressure. When all three work together, the process becomes more efficient and easier to manage in the field.
