In particularly tough cases, the pickling technique is the only way of achieving the desired success.

The pickling technique is used to deal with surface scale formation or severe heat discoloration on welding seams and in the presence of heavy surface corrosion. Pickling generally involves the employment of more aggressive chemicals. Pickling solutions can have a cleaning effect but they may also remove material. In special cases we conduct preliminary tests in our laboratory and develop the right reaction solution on the basis of the results. By adjusting the pickling effect to the desired cleaning outcome and a targeted precisely dosed use of the pickling chemicals we guarantee optimum cleaning without placing any excessive burden on the environment and materials. In this way, sustainable rust removal is possible – from straightforward room walls and also from pipeline systems running over several kilometres.
