For local pickling and cleaning all types of welds. Remains active with temperatures >10°C 

Degrease thoroughly the surface with RXSOL-10-1005-025 . Never let the product dry. Hose off completely and thoroughly with a high-pressure spraying pistol. Remaining grease and product will influence the pickling process adversely. Let the surface dry, rub dry or blow dry.

Stir the pickling paste. Spread the undiluted paste over the surface or the weld by using the supplied acid resistant brush.

Contact time: 30 min to 2 h. (depending on the kind of weld, the room temperature and material).The pickling process is terminated as soon as the paste turns green. Always rinse abundantly with clean water. Rinse preferably with demineralised water.

Never let the product dry Prolonged pickling lead to accelerated corrosion sensitivity and damages the passivation process

In case of doubt, try out on a test surface or contact our technical service.
