THE ANSWER TO BRICK CLEANING
The Citation Model 4000 has the capability of cleaning over 3,500 brick in an hour without sanding the joints or breaking the weather seal. It can also clean white brick with colored mortar.
The Model 4000 Acid/Hot High Pressure Washer is designed to precisely meter acids and other additives, then mix them at the special nozzle with 180 GPH of 210° F. water in a 1200 PSI discharge stream.
When there is a question about brick cleaning or building restoration, this unit is the answer. You can see this unique cleaning system at Booth 40 during the Mason Contractors Association of America Show in New Orleans.
